Which of the following statement is correct ?

Which of the following statement is correct ?

Options

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

Correct answer

A. +I+I group stabilises a carbocation

Step-by-step solution

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