An allyl is a substituent with the molecular formula H2C=CH−CH2R. It consists of a radical bridge (−CH2−) hooked up to a vinyl radical (−CH=CH2). The name springs from the Latin word for garlic, Allium sativum. In 1844, Theodor Wertheim isolated an allyl group by-product from garlic oil and named it "Schwefelallyl. The term allyl group applies to several compounds associated with H2C=CH−CH2, a number of that square measure of sensible or of everyday importance, as an example, allyl group chloride. The allyl is wide encountered in chemical science. Radicals, anions, and cations square measure usually mentioned as intermediates in reactions. All feature 3 contiguous sp²-hybridized carbon centres and every one derive stability from resonance. Every species will be bestowed by 2 resonance structures with the charge or mismatched lepton distributed at each one,3 positions. Allylation is any chemical action that adds an allyl to a substrate
