Question

Order these carbocations from most stable (1) to least stable. (5) If there is resonance, that can make the carbocation more stable than if there isn't; for example, primary benzylic is more stable than primary allylic, which is more stable than secondary, as a general rule.

Answer 1

Explanation :

benzylic carbo cation is most stable among the all .

the order of carbo cations from most to least stable :

benzylic > allylic > tertiary > secondary   > primary .

A = benzylic

B = tertiary

C = primary

D = allylic

E = secondary
