Allyl as a functional group is represented as-CH 2 -CH=CH 2. Allyl is considered to be a common name. The term allyl deals with a carbon attached to a carbon in a double bond (that is sp2 hybridized).This is not to be confused with allylic as allylic refers to just a carbon attached to the carbon in the double bond, not the entire group of three carbons.he vinyl group is similar to the allyl group. However, vinyl refers to a group attached directly to an sp 2 hybridized (double bonded) carbon. The vinyl group is represented as-CH=CH 2. This is not to be confused with vinyllic carbons which are only the carbons participating in the double bond, not the entire group.
3. Carbon can form double and triple bonds with other carbon atoms or other elements. 4. Carbon can bond with itself either as straight chains or cyclic compounds with branching possible in either case. Two different organic compounds can also have the same number of carbon atoms.These are called isomers.Isomers are molecules that have the same molecular formulas but different structures and thus different physical and chemical characteristics. An example of isomerism is butane and 2-methylpropane.. Carbon can form double and triple bonds with other carbon atoms or other elements. 4. Carbon can bond with itself either as straight chains or cyclic compounds with branching possible in either case. Two different organic compounds can also have the same number of carbon atoms.
