A) 1 > 2 > 3 > 4
B) 4 > 3 > 2 > 1
C) 1 > 2 > 4 > 3
D) 4 > 1 > 2 > 3
Correct Answer: B
Solution :
The stability of the carbanion decreases with increase in number of alkyl groups. However, phenyl group stabilizes the carbanion due to resonance effect. \[\therefore \] The order of stability of given ions is as follows \[{{C}_{6}}{{H}_{5}}\bar{C}{{H}_{2}}>C{{H}_{3}}\bar{C}{{H}_{2}}>{{(C{{H}_{3}})}_{2}}\bar{C}H>{{(C{{H}_{3}})}_{3}}\bar{C}\]or \[4>3>2>1\]
