Allylic strain (also known as A strain, 1,3-allylic strain, or A-strain) in organic chemistry is a type of strain energy resulting from the interaction between a substituent on one end of an olefin (a synonym for an alkene) with an allylic substituent on the other end. If the substituents (R and R') are large enough in size, they can sterically interfere with each other such that one conformer is gre… WebFeb 14, 2024 · Più importante del gruppo allile è l'unità allilica che è la stessa per tutti i composti allilici.
