PAHs Polycyclic aromatic hydrocarbons (PAHs) are a group of over 100 chemicals formed during the incomplete burning of coal, oil, gas, wood, garbage, and other organic substances such as tobacco and charbroiled meat. [2-4] Refer to the IARC Monograph for the complete list of chemicals classified under the PAH group. [2].

Heterocyclic Compounds Several methods of preparing four-membered heterocyclic compounds are shown in the following diagram. The simple procedure of treating a 3-halo alcohol, thiol or amine with base is generally effective, but the yields are often mediocre. Dimerization and elimination are common side reactions, and other functions may compete in the reaction.

Aliphatic compound Structure [edit]. Aliphatic compounds can be saturated, joined by single bonds (alkanes), or unsaturated, with double bonds (alkenes) or triple bonds (alkynes). Besides hydrogen, other elements can be bound to the carbon chain, the most common being oxygen, nitrogen, sulphur, and chlorine.n 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

Heterocyclic compound A heterocyclic compound or ring structure is a cyclic compound that has atoms of at least two different elements as members of its ring(s). Heterocyclic chemistry is the branch of organic chemistry dealing with the synthesis, properties, and applications of these heterocycles.

- Ionic compounds are compounds composed of ions, charged particles that form when an atom (or group of atoms, in the case of polyatomic ions) gains or loses electrons. A cation is a positively charged ion.

- Ch16 Aromatic Compounds (landscape).docx page 20 Aromatic compounds are more stable than their open chain counterparts. For example, benzene is more stable than 1,3,5-hexatriene. An antiaromatic compound is less stable than its open chain counterpart. For example, cyclobutadiene is less stable than butadiene.

COORDINATION CHEMISTRY 1 Coordination compounds are complexes that consist of one or more central atoms or ions with one or more attached molecules. 2  The central atom is called a metal, and is a Lewis Acid;  The attached ions are ligands, and are Lewis Bases;

- Coordination Complexes. Coordination compounds, such as the FeCl4- ion and CrCl3 6 NH3, are called such because they contain ions or molecules linked, or coordinated, to a transition metal. They are also known as complex ions or coordination complexes because they are Lewis acid-base complexes. The ions or molecules that bind to transition-metal ions to form these complexes are called ligands (from Latin, to tie or bind).

- Although PAH is not very well known to the general public, everyone one can be exposed to it through many different pathways. Polycyclic Aromatic Hydrocarbons (PAH) are molecules made from carbon and hydrogen. PAH is comes into being when materials are burned, these materials include wood, oil, charcoal and tobacco.PAH is even present in some of our own household products such as mothballs, some shampoos and skin creams.lthough PAH is not very well known to the general public, everyone one can be exposed to it through many different pathways.

Occupational Safety and Health Administration Isocyanates are compounds containing the isocyanate group (-NCO). They react with compounds containing alcohol (hydroxyl) groups to produce polyurethane polymers, which are components of polyurethane foams, thermoplastic elastomers, spandex fibers, and polyurethane paints.

Polycyclic Aromatic Hydrocarbons (PAHs) Polycyclic aromatic hydrocarbons (PAHs) are a group of over 100 different chemicals that are formed during the incomplete burning of coal, oil and gas, garbage, or other organic substances like tobacco or charbroiled meat. PAHs are usually found as a mixture containing two or more of these compounds, such as soot.

Learn more about Aliphatic Compounds Alicyclic compounds refer to aliphatic compounds (saturated or unsaturated) in which some of the carbon atoms are in a ring formation (cycle), but may not be a benzenoid or other aromatic system [20]. Saturated alicyclic hydrocarbons go by several names, including cycloalkanes, cycloparaffins, and naphthenes.

Heterocyclic Compounds Heterocyclic rings are found in many naturally occurring compounds. Most notably, they compose the core structures of mono and polysaccharides, and the four DNA bases that establish the genetic code. By clicking on the above diagram some other examples of heterocyclic natural products will be displayed.

Inorganic compound Inorganic compound, any substance in which two or more chemical elements (usually other than carbon) are combined, nearly always in definite proportions. Compounds of carbon are classified as organic when carbon is bound to hydrogen. Carbon compounds such as carbides (e.g., silicon carbide [SiC2]), some carbonates (e.g., calcium carbonate [CaCO3]), some cyanides (e.g., sodium cyanide [NaCN]), graphite, carbon dioxide, and carbon monoxide are classified as inorganic. See chemical compound: Inorganic compounds.

Energy, chemical reactions and organic compounds Organic chemistry is the study of compounds containing carbon. The four primary categories of organic compounds are: Carbohydrates, lipids, proteins, nucleotides and nucleic acids. Carbon has only 4 valence electrons, they bond readily to gain more valence electrons. Carbon can form long chains, branched molecules and rings, these serve as the backbone for organic molecules.

Gallium trichloride Gallium trichloride is the chemical compound with the formula GaCl 3. Solid gallium trichloride exists as a dimer with the formula Ga 2 Cl 6. It is colourless and soluble in virtually all solvents, even alkanes, which is truly unusual for a metal halide. It is the main precursor to most derivatives of gallium and a reagent in organic synthesis. As a Lewis acid, GaCl 3 is milder than aluminium trichloride. Gallium(III) is easier to reduce than Al(III), so the chemistry of reduced gallium compounds is more extensive than for aluminium. Ga 2 Cl 4 is known whereas the corresponding Al 2 Cl 4 is not.

Naming Ionic Compounds: Simple Binary, Transition Metal & Polyatomic Ion Compounds A polyatomic ionic compound is a compound made up of a polyatomic ion, which is two or more atoms bonded together, and a metal. Naming polyatomic ions is harder, but doable. First, name the cation, which is just the name of the element. Next, name the anion.

- Polycyclic aromatic hydrocarbons (PAHs) are a class of chemicals that occur naturally in coal, crude oil, and gasoline. They also are produced when coal, oil, gas, wood, garbage, and tobacco are burned. PAHs generated from these sources can bind to or form small particles in the air.

tetracycline See tetracycline defined for kids. Most chemical names are made up of two or more Greek and Latin roots strung together. Thus, tetracycline, with its cycl- root from the Greek word for circle, means four-ringed—that is, consisting of four fused hydrocarbon rings.

Formulas and Nomenclature of Ionic and Covalent Compounds Ionic compounds are compounds composed of ions, charged particles that form when an atom (or group of atoms, in the case of polyatomic ions) gains or loses electrons. 1  A cation is a positively charged ion. 2  An anion is a negatively charged ion.

Naming Organic Compounds Hydrocarbons having more than one ring are common, and are referred to as bicyclic (two rings), tricyclic (three rings) and in general, polycyclic compounds. The molecular formulas of such compounds have H/C ratios that decrease with the number of rings.f more than one double bond is present the compound is named as a diene, triene or equivalent prefix indicating the number of double bonds, and each double bond is assigned a locator number. 5. In cycloalkenes the double bond carbons are assigned ring locations #1 and #2.
