Arrange the ortho (I), meta (II) and para (III) aminobenzyl carbanions in decreasing order of stability.

(I) structure (II) (III)

Options:

Answer:

Solution:

$N H_{2}$ is a +R donor from ortho and para, which destabilises the negative charge. At meta only the -I effect acts, which stabilises the anion, so meta is the most stable.

The -I effect is stronger at ortho, so ortho $>$ para.

Order : II $>$ I $>$ III.
