Q86 / 160 · JIPMER 2010 · Chemistry

Which of the following statement is correct ?

  • Correct answer
    A
    $+I$ group stabilises a carbocation
  • B
    $+I$ group stabilises a carbanion
  • C
    $-I$ group stabilises a carbocation
  • D
    $-I$ group stabilises a free radical

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.

Hence, the correct answer is option: 'A'.
