Aromatic hydrocarbon An aromatic hydrocarbon or arene (or sometimes aryl hydrocarbon) is a hydrocarbon with sigma bonds and delocalized pi electrons between carbon atoms forming rings.enzene, C 6 H 6, is the simplest aromatic hydrocarbon, and it was the first one named as such. The nature of its bonding was first recognized by August Kekule kekulé in the 19th. century

Incense Incense. ( 1  Latin thus , Gr. thumiama ), an aromatic substance which is obtained from certain resinous trees and largely employed for purposes of religious worship. The word is also used to signify the smoke or perfume arising from incense when burned.

- Hydrocarbons derived from petroleum, characterized by a ring-like molecular structure and 'sweet' or aromatic odor. Benzene, tolune, and xylene are the most common aromatics, and are used as chemical feedstocks, solvents, and as additives to gasoline to raise its octane rating.

Aliphatic compound In organic chemistry, compounds composed of carbon and hydrogen are divided into two classes: aromatic compounds and aliphatic compounds (/ˌaelɨˈfaetɨk/ ; ˌælɨˈfætɨk. g, aleiphar, fat) oil also known as-non aromatic. compounds

Benzene Benzene is a natural constituent of crude oil, and is one of the most elementary petrochemicals. Benzene is an aromatic hydrocarbon and the second [ n ]- annulene ([6]-annulene), a cyclic hydrocarbon with a continuous pi bond.erivatives of benzene occur sufficiently often as a component of organic molecules that there is a Unicode symbol in the Miscellaneous Technical block with the code U+232C (⌬) to represent it with three double bonds, and U+23E3 (⏣) for a delocalized version.

aromatherapy Aromatherapy is the therapeutic use of plant-derived, aromatic essential oils to promote physical and psychological well-being. It is sometimes used in combination with massage and other therapeutic techniques as part of a holistic treatment approach.

Leafly Glossary of Cannabis Terms Aroma is a term used to describe the general smell and/or taste of a certain plant or flower. Because consumers' individual definition of aromas (such as  earthy , skunky , or  citrus ) can differ somewhat, aroma descriptions are meant as a basic guideline.

Overview Aromatherapy is the use of organic compounds to improve your mood, mental state, or health. Those organic compounds are called essential oils. They’re made from various plant parts, such as roots, seeds, leaves, and blossoms.

- Functional Groups - Aromatics. Aromatics. Compounds containing benzene rings (see above) are aromatic compounds. If there are other groups present on the benzene ring the compound is said to be a substituted benzene. The chemical properties of substituted benzenes are determined both by the aromatic groups and by the properties of the group bonded to the ring. In most instances, the presence of the benzene ring will not interfere with chemical tests (discussed later) for the groups bonded to the ring. For example, benzaldehyde, which contains both an aldehyde group and a benzene ring, would give positive tests for both an aromatic compound and for an aldehyde.

Polycyclic aromatic hydrocarbon Polycyclic aromatic hydrocarbons are hydrocarbons—organic compounds containing only carbon and hydrogen—that are composed of multiple aromatic rings. Formally, the class is further defined as lacking further branching substituents on these ring structures. The simplest such chemicals are naphthalene, having two aromatic rings, and the three-ring compounds anthracene and phenanthrene. PAHs are non-charged, non-polar molecules found in coal and in tar deposits. They are also produced by ...

- Incense is aromatic biotic material which releases fragrant smoke when burned. The term refers to the material itself, rather than to the aroma that it produces. Incense is used for a variety of purposes, including the ceremonies of religion, to overcome bad smells, repel insects, spirituality, aromatherapy, meditation, and for simple pleasure. Incense is composed of aromatic plant materials, often combined with essential oils. The forms taken by incense differ with the underlying culture, and have changed with advances in technology and increasing diversity in the reasons for burning it.

Aromatic hydrocarbon The configuration of six carbon atoms in aromatic compounds is known as a benzene ring, after the simplest possible such hydrocarbon, benzene. Aromatic hydrocarbons can be monocyclic (MAH) or polycyclic (PAH). Some non-benzene-based compounds called heteroarenes, which follow Hückel's rule (for monocyclic rings: when the number of its π-electrons equals 4n + 2, where n = 0, 1, 2, 3…), are also called aromatic compounds.

Benzene and Other Aromatic Compounds Benzene is the archetypical aromatic compound. It is planar, bond angles=120º, all carbon atoms in the ring are sp 2 hybridized, and the pi-orbitals are occupied by 6 electrons. The aromatic heterocycle pyridine is similar to benzene, and is often used as a weak base for scavenging protons.he resulting planar ring meets the first requirement for aromaticity, and the π-system is occupied by 6 electrons, 4 from the two double bonds and 2 from the heteroatom, thus satisfying the Hueckel Hückel. Rule four illustrative examples of aromatic compounds are shown. above

fragrance A fragrance is a smell, usually a pleasant or sweet smell. Often perfumes are called fragrances. If you like the fragrance of coffee, you like its smell. Unlike the word odor, which usually means a bad smell, fragrances are usually good smells. People love the fragrance of flowers and good food. A specific smell can also be called a fragrance.

What's the difference between anti-aromatic and non aromatic compounds? Aromatic compounds are those that have (4n + 2) pi electrons within them. e.g. Benzene has 6 pi electrons, therefore n=1 for benzene. Some molecules can be anti-aromatic in which case they just have 4n pi electrons.If a molecule is neither it is simply (non-aromatic).orks for conjugated ring system with 4n + 2 pi-electrons (benzene, 6; naphthalene, 10) Antiaromatic; this happens with conjugated ring systems with 4n pi-electrons.

Aroma compound Fragrance bottles. An aroma compound, also known as an odorant, aroma, fragrance, or flavor, is a chemical compound that has a smell or odor. A chemical compound has a smell or odor when it is sufficiently volatile to be transported to the olfactory system in the upper part of the nose. Generally molecules meeting this specification have molecular weights of <300.

Benzene Benzene is a natural constituent of crude oil, and is one of the most elementary petrochemicals. Benzene is an aromatic hydrocarbon and the second [ n ]- annulene ([6]-annulene), a cyclic hydrocarbon with a continuous pi bond.he most common reactions of benzene involve substitution of a proton by other groups. Electrophilic aromatic substitution is a general method of derivatizing benzene. Benzene is sufficiently nucleophilic that it undergoes substitution by acylium ions and alkyl carbocations to give substituted derivatives.

All about Essential Oils!! All about Essential Oils!! Essential Oils are a concentrated, hydrophobic liquid, containing volatile aroma compounds from plants. Essential oils are also known as volatile oils, ethereal oils or aetherolea, or simply as the oil of the plant from which they were extracted, such as oil of clove. An oil is essential in the sense that it carries a distinctive scent, or essence, of the plant. Essential oils are generally extracted by distillation.

What are aromatics in cooking? Aromatics are herbs, spices and vegetables (and sometimes meat) that are cooked in oil as a base for the flavor of a dish. Cooking them in oil helps to release their flavors and aromas, creating a deep flavor foundation for soups, stews, sauces, meat fillings and more. Most cuisines have a traditional combination of aromatics.

What does Fragrance really mean? Perfume is a fragrant liquid made from essential oils extracted form flowers and spices, so nothing chemical about it. * Dermatitis: A condition of the skin in which it becomes red, swollen, and sore, sometimes with small blisters, resulting from direct irritation of the skin by an external agent or an allergic reaction to it.
