How do you know if a molecule has a single, double, or triple bond? Your first step should be to analyse the compound. For example, if the compound is carbon, you know it always has a valence of four, so, if it has a formula C2H4 (ethylene) it obviously has a double bond. There are difficulties here because benzene C6H6 can be considered to have 6 1.5 C-C bonds, being aromatic.

CHEMISTRY: Double and Triple Bond? Look at the number of bonding domains. for example, Calcium has a charge of +2 and oxygen has a charge of -2. They bond, and calcium gives up 2 electrons to the same oxygen, creating a double bond, forming a binary compound (Calcium Oxide) It all depends on the elements. The main thing is the number of electrons being transfered.

- Chemical bonding between atoms results in compounds that can be very different from the parent atoms. This module, the second in a series on chemical reactions, describes how atoms gain, lose, or share electrons to form ionic or covalent bonds.The module lists features of ionic and covalent compounds. good example of a polar covalent bond is the hydrogen-oxygen bond in the water molecule. Water molecules contain two hydrogen atoms (pictured in red) bonded to one oxygen atom (blue). Oxygen, with six valence electrons, needs two additional electrons to complete its valence shell. Each hydrogen contains one electron.

- Any bond between two atoms of the same element is a nonpolar covalent bond in which electrons are shared equally and electron clouds have an even density. The hydrogen molecule and the chlorine molecule are two examples. Two oxygen atoms will come together to form a double nonpolar covalent bond.This means that they share four electrons between them, but still do so evenly. Two nitrogen atoms bond to form the nitrogen molecule with a triple nonpolar covalent bond.wo oxygen atoms will come together to form a double nonpolar covalent bond. This means that they share four electrons between them, but still do so evenly. Two nitrogen atoms bond to form the nitrogen molecule with a triple nonpolar covalent bond.

Chapter 5.3: Lewis Structures To give carbon an octet of electrons, we use one of the lone pairs of electrons on oxygen to form a carbon–oxygen double bond: Both the oxygen and the carbon now have an octet of electrons, so this is an acceptable Lewis electron structure. The O has two bonding pairs and two lone pairs, and C has four bonding pairs. This is the structure of formaldehyde, which is used in embalming fluid.

- Compound #2 has a double bond between carbons 3 and 4, making it an alkene. It has 7 carbon atoms, so we would simply indicate the location of the double bond and call it 3-heptene. Compound #3, I am assuming the lone CH3 is misplaced and should be directly above the next-to-last carbon (CH), which would make sense.

Explain the Octet Rule & Give Examples Many elements are not chemically stable by themselves; by sharing electrons, an atom gains stability. In a chemical formula, the octet rule strongly governs the number of atoms for each element in a molecule; for example, calcium fluoride is CaF2 because two fluorine atoms and one calcium satisfy the rule.or the carbon dioxide molecule, for example, one carbon atom bonds with two oxygen atoms. Carbon, with four electrons in its valence shell, needs four to reach the octet state. Oxygen, with six outer electrons, needs two.

Alkenes and alkynes Alkenes and alkynes. Hydrocarbons with only CC single bonds are known as saturated hydrocarbons. If a hydrocarbon contains double and/or triple bonds, it is known as unsaturated. The molecule ethylene (C H) contains a carbon double bond and is officially referred to as ethene, although the name ``ethylene'' is more commonly used. Similarly, the molecule acetylene (C H) contains a carbon triple bond and has the official name ethyne. In general, alkenes contain double bonds and alkynes contain triple bonds. If the main carbon chain contains more than three carbons, it is necessary to specify where on the chain the double or triple bond occurs.

Alkene In organic chemistry, an alkene is an unsaturated hydrocarbon that contains at least one carbon –carbon double bond. Alkene, olefin, and olefine are used often interchangeably (see nomenclature section below).Acyclic alkenes, with only one double bond and no other functional groups, known as mono-enes, form a homologous series of hydrocarbons with the general formula C n H 2n.ike a single covalent bond, double bonds can be described in terms of overlapping atomic orbitals, except that, unlike a single bond (which consists of a single sigma bond), a carbon–carbon double bond consists of one sigma bond and one pi bond.

- Alkenes and Alkynes - unsaturated hydrocarbons Double bonds in hydrocarbons are indicated by replacing the suffix -ane with -ene. If there is more than one double bond, the suffix is expanded to include a prefix that indicates the number of double bonds present (-adiene, -atriene, etc.). Triple bonds are named in a similar way using the suffix -yne. The position of the multiple bond(s) within the parent chain is(are) indicated by placing the number(s) of the first carbon of the multiple bond(s) directly in front of the base name. Here is an important list of rules to follow:

Chemical Bonds Examples A common example of a compound with an ionic bond is table salt. Table salt has the formula NaCl and is formed because the sodium, Na forms a positive ion and the chlorine, Cl forms a negative ion. The two ions are then attracted to each other to form the ionic bond.he octet can be satisfied through the sharing of electrons or through the process of giving away and accepting electrons to form chemical bonds. Examples of Chemical Bonds: 1. Single covalent bonds form when only one pair of electrons are shared between atoms. This is very common with elements that are non-metallic.
