Question

Arrange the carbanions, $${\left( {C{H_3}} \right)_3}\overline C ,\overline C C{l_3},{\left( {C{H_3}} \right)_2}\overline C H,{C_6}{H_5}\overline C {H_2}$$         in order of their decreasing stability :

A. $${\left( {C{H_3}} \right)_2}\overline C H > \overline C C{l_3} > {C_6}{H_5}\overline C {H_2} > {\left( {C{H_3}} \right)_3}\overline C $$
B. $$\overline C C{l_3} > {C_6}{H_5}\overline C {H_2} > {\left( {C{H_3}} \right)_2}\overline C H > {\left( {C{H_3}} \right)_3}\overline C $$  
C. $${\left( {C{H_3}} \right)_3}\overline C > {\left( {C{H_3}} \right)_2}\overline C H > {C_6}{H_5}\overline C {H_2} > \overline C C{l_3}$$
D. $${C_6}{H_5}\overline C {H_2} > \overline C C{l_3} > {\left( {C{H_3}} \right)_3}\overline C > {\left( {C{H_3}} \right)_2}\overline C H$$
Answer :   $$\overline C C{l_3} > {C_6}{H_5}\overline C {H_2} > {\left( {C{H_3}} \right)_2}\overline C H > {\left( {C{H_3}} \right)_3}\overline C $$
