For carbanion Stability order will be
Options
- AP Q S R
- BP R Q S
- CQ R S R
- DS R Q P
Correct answer
B. P R Q S
Step-by-step solution
As -M and -I -effect increase, stability of carbanion increases. -M -effect is possible only at ortho and para-position and -I -effect is more pronounced at ortho position. Hence, correct order of stability is
