Question

The stability of carbanions in the following
(i) `RC-=overset(-)overset(..)C` , (ii)
(iii) `R_(2)C=overset(-)overset(..)CH` , (iv) `R_(3)C-overset(-)overset(..)CH_(2)`
is in the order
A. `(iv) gt (ii) gt (iii) gt (i)`
B. `(i) gt (iii) gt (ii) gt (iv)`
C. `(i) gt (ii) gt (iii) gt (iv)`
D. `(ii) gt (iii) gt (iv) gt (i)`

Answer 1

Correct Answer - B
Higher is the electronegativity of atom higher will be stability of carbanion on it. Higher is the s-character, higher will be the electronegativity of atom.
