Question

What is the decreasing reactivity order of the following compounds A) Acetone B) Ethanal C) 2,2-dimethyl-2-butanone D) 2,2,4-trimethyl-3-petanone E) 2-methylpropanal O B, E, A, C, D O E, B, C, A, D O D, C, A, E,B O E, B,A,C,D OD,A,C,BE

Answer 1

Answer: B,E,A,C,D

Aldehydes are more reactive than ketones. So here B and E are aldehydes, in that B, is ethanal more reactive than E, 2-methyl propanal due to more releasing groups present in compound the electrophilic nature of carbonyl decreases, So B>E.

Remaining all are ketones in that A, actone is more reactive due to less number of releasing groups.

So, ans: B,E,A,C,D
