Which of the following statement is correct ?

Options

  1. A+I group stabilises a carbocation
  2. B+I group stabilises a carbanion
  3. C-I group stabilises a carbocation
  4. D-I group stabilises a free radical

Correct answer

A. +I group stabilises a carbocation

Step-by-step solution

+I group (ie, electron donating groups) stabilised the carbocation. +I and -I groups destabilised the carbanion and carbocations respectively. +I groups stabilised the free radicals but -I group destabilised them.
