Electrophilic additions reactions procee...

Electrophilic additions reactions proceed in two steps. The first step involves the additions of an electrophile. Name the type of intermediate formed in the first step of the following addition reaction `H_(3)C - HC = CH_(2) + H^(+) rarr`?

A

`3^(@)` carbanion

B

`1^(@)` carbocation

C

`2^(@)` carbocation

D

`1^(@)` carbanion

Text Solution

Verified by Experts

The correct Answer is:
C

When electrophile attackes `CH_(3) - CH = CH_(2)` delocalisation of electrons can take place, in two possible ways

As `2^(@)` carbocation is more stable than `1^(@)` carbocations thus first additions is more feasible
Note. Stability of carbocations is the basis of Markownikoff's rule
