1.	Which of the following is not a suitable initiator for free radical addition polymerisation reaction?(a) Acetyl peroxide(b) Benzoyl peroxide(c) tert-Butyl peroxide(d) BenzoquinoneThis question was posed to me during an interview.The doubt is from Types of Polymerisation Reactions in portion Polymers of Chemistry – Class 12
Answer» The correct answer is (d) Benzoquinone The explanation: Benzoquinone combines with the FREE radical intermediate to form a highly STABLE, non-reactive radical because of resonance. This inhibits the further progress of the CHAIN growth and therefore, the reaction stops. Peroxides are very important free radical generating INITIATORS.
