MO diagram for pi-orbitals on the allyl radical.  The middle MO labeled Ψ2 is singly occupied in the allyl radical.  In the allyl cation Ψ2 is unoccupied and in the allyl anion it is doubly occupied.  Hydrogen atoms are omitted from this picture.

An allyl group is a substituent with the structural formula H2C=CH-CH2R, where R is the rest of the molecule. It consists of a methylene bridge (-CH2-) attached to a vinyl group (-CH=CH2). 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". The term allyl applies to many compounds related to H2C=CH-CH2, some of which are of practical or of everyday importance for example allyl chloride.
