Alkyl Aryl Vinyl

The key difference between these two structural components is the number of carbon and hydrogen atoms.

Alkyl aryl vinyl.

Both groups own a double bond between two carbon atoms where all the other atoms are bonded through single bonds. Key difference allyl vs vinyl both allyl and vinyl groups have slightly similar structures with a small variation. Allyl indicates a functional group with structural formula h 2 c ch ch 2 r where r is the rest of the molecule it consists of methylene bridge ch 2 in between the vinyl group ch ch 2 and the rest of the molecule therefore allyl group contains sp 2 hybridized vinyl carbon atoms and sp 3 hybridized allyl carbon atom. Vinylic carbocations are unstable as compare to the allyl carbocations as they lack p character.

The allylic carbon atom is more reactive than normal. The most basic aryl group is phenyl which is made up of a benzene ring with one hydrogen atom substituted for some substituent and has the molecular formula c 6 h 5. The vinyl compounds are every reactive and they polymerize to form the vinyl polymers as in the case of polyvinyl acetate polyvinyl chloride and polyvinyl fluoride. Allyl groups have three carbon atoms and five hydrogen atoms.

An aryl halide has general formula c 6h 5x in which an halide group x has substituted the aryl ring. Note that phenyl groups are not the same as benzyl groups which consists of a phenyl group attached to a methyl group and has the molecular formula c 6 h 5 ch 2. Enamides and enol ethers are valuable building blocks in synthetic chemistry yet their stereoselective synthesis can be challenging.
