Allylic Hydrogen Vinyl Hydrogen. Benzylic position allylic position propargylic position aryl aryl hydrogen. This molecule has four vinylic positions each marked with. An allyl group is a substituent with the structural formula h 2 c ch ch 2 r where r is the rest of the molecule.
Vinyl group vinylic hydrogen vinylic carbocation allylic position benzylic position propargylic position. Key difference allyl vs vinyl both allyl and vinyl groups have slightly similar structures with a small variation.
Allyl group consists of ch 2 methylene bridge and is attached with ch ch 2 vinyl group.
The name is derived from the latin word for garlic allium sativum in 1844 theodor wertheim isolated an allyl derivative from garlic oil and named it schwefelallyl. An allyl derivative was first found within the garlic oil by theodor wertheim in 1844 he named it schwefelallyl. Carbon atom and double bond.
