Arrange the ortho (I), meta (II) and para (III) nitrobenzyl carbanions in decreasing order of stability.
(I) 
(II) 
(III) 
Options:
Answer:
D
Solution:
NO₂ is a -M and -I group, so it stabilises a benzylic carbanion. The -M effect acts only from ortho and para, so meta is the least stable.
The -I effect is stronger at the nearer ortho position, so ortho para.
Order : I III II.
