Arrange the carbanions, (CH(3))(3)bar(C)...

Arrange the carbanions, `(CH_(3))_(3)bar(C),bar(C)Cl_(3),(CH_(3))_(2)bar(C)H,C_(6)H_(5)bar(C)H_(2)`, in order of their decreasing stability

A

`III gt II gt IV gt I`

B

`II gt IV gt III gt I`

C

`I gt III gt IV gt I`

D

`IV gt II gt I gt III`

Text Solution

Verified by Experts

The correct Answer is:
B
`Cl_(3)overset(-)overset(..)` is the most stable as it is stabilized by `d`-orbital resonance and its resonance structures carry negative charge on the more electronegative `Cl` atoms.
