The order of decreasing stability of the following carbanions is (i) (CH_(3))_(3)C^(-) (ii) (CH_(3))_(2)CH^(-) (iii) CH_(3)CH_(2)^(-) (iv) C_(6)H_(5)CH_(2)^(-)

The order of decreasing stability of the following carbanions is (i)

1.	The order of decreasing stability of the following carbanions is (i) (CH_(3))_(3)C^(-) (ii) (CH_(3))_(2)CH^(-) (iii) CH_(3)CH_(2)^(-) (iv) C_(6)H_(5)CH_(2)^(-)
Answer» (i)GT(ii)gt(iii)gt(iv) (iv)gt(iii)gt(ii)gt(i) (iv)gt(i)gt(ii)gt(iii) (iii)gt(ii)gt(i)gt(Iv) Solution :Stability of carbanions decreases with increase in `+I` effect. +I effect is maximum in `(CH_(3))_(3)C^(-)`, followed by `(CH_(3))_(2)CH^(-) and CH_(3)CH_(2)^(-)`. In `C_(6)H_(5)CH_(2)^(-)`, RESONANCE effect increases the stability. Hence, the order of stability is (iv)gt(iii)gt(ii)gt(i)
