Given below are two statements:

Statement I: In

the carbocation is stabilised by +R effect of

- OCH_{3}

group.

Statement II : In

the carbanion is stabilised by -R effect of

- NO_{2}

group.

In the light of the above statements, choose the correct answer from the options given below :

(A)Both Statement I and Statement II are true✓ Correct
(B)Both Statement I and Statement II are false
(C)Statement I is true but Statement II is false
(D)Statement I is false but Statement II is true

Answer: (A)

Solution

In the first species the positive charge sits on a benzylic carbon carrying a para-methoxyphenyl ring; the lone pair on the methoxy oxygen feeds through the ring onto the cationic carbon, so the

+ R

effect of

- OCH X_{3}

stabilises the carbocation and Statement I is correct. In the second species the negative charge sits on a benzylic carbon carrying a para-nitrophenyl ring; the

- NO X_{2}

group draws this charge into its own

π

system by resonance, so the

- R

effect of

- NO X_{2}

stabilises the carbanion and Statement II is correct. Both statements are true.
