Question

Arrange the carbanions, $(CH_3)_3\overset{-}{C}, \overset{-}{C}Cl_3, (CH_3)_2\overset{-}{C}H, C_6H_5\overset{-}{C}H_2$ in order of their decreasing stability :
(a) $(CH_3)_2\overset{-}{C}H \ \textgreater \ \overset{-}{C}Cl_3 \ \textgreater \ C_6H_5\overset{-}{C}H_2 \ \textgreater \ (CH_3)_3\overset{-}{C}$
(b) $\overset{-}{C}Cl_3 \ \textgreater \ C_6H_5\overset{-}{C}H_2 \ \textgreater \ (CH_3)_2\overset{-}{C}H \ \textgreater \ (CH_3)_3\overset{-}{C}$
(c) $(CH_3)_3\overset{-}{C} \ \textgreater \ (CH_3)_2\overset{-}{C}H \ \textgreater \ C_6H_5\overset{-}{C}H_2 \ \textgreater \ \overset{-}{C}Cl_3$
(d) $C_6H_5\overset{-}{C}H_2 \ \textgreater \ \overset{-}{C}Cl_3 \ \textgreater \ (CH_3)_3\overset{-}{C} \ \textgreater \ (CH_3)_2\overset{-}{C}H$
