Allyl group - Wikipedia
In organic chemistry, an allyl group is a substituent with the structural formula −CH 2 −HC=CH 2. It consists of a methylene bridge ( −CH 2 − ) attached to a vinyl group ( −CH=CH 2 ). [ 1 ] [ 2 ] The name is derived from the scientific name for garlic , Allium sativum .

Allyl System. Let’s take a look at the simplest system that has conjugation – where electrons can be delocalized over three atoms. This is known as the allyl system. Notice that there is never any way to place the –, +, or * on the central carbon atom! Why? Let’s construct the molecular orbitals for the allyl group’s \(π\) system. 1.
