Question

Arrange the carbanions, ${\left( {{\rm{C}}{{\rm{H}}_3}} \right)_3}\mathop {\rm{C}}\limits^\_ ,\mathop {\rm{C}}\limits^\_ {\rm{C}}{{\rm{l}}_3},{\left( {{\rm{C}}{{\rm{H}}_3}} \right)_2}\mathop {\rm{C}}\limits^\_ {\rm{H}},{{\rm{C}}_6}{{\rm{H}}_5}\mathop {\rm{C}}\limits^\_ {{\rm{H}}_2}$, in order of their decreasing stability

Accepted Answer

$\mathop {\rm{C}}\limits^\_ {\rm{C}}{{\rm{l}}_3} > {{\rm{C}}_6}{{\rm{H}}_5}\mathop {\rm{C}}\limits^\_ {{\rm{H}}_2} > {\left( {{\rm{C}}{{\rm{H}}_3}} \right)_2}\mathop {\rm{C}}\limits^\_ {\rm{H}} > {\left( {{\rm{C}}{{\rm{H}}_3}} \right)_3}\mathop {\rm{C}}\l

Answer

${{\rm{C}}_6}{{\rm{H}}_5}\mathop {\rm{C}}\limits^\_ {{\rm{H}}_2} > \mathop {\rm{C}}\limits^\_ {\rm{C}}{{\rm{l}}_3} > {\left( {{\rm{C}}{{\rm{H}}_3}} \right)_2}\mathop {\rm{C}}\limits^\_ > {\left( {{\rm{C}}{{\rm{H}}_3}} \right)_2}\mathop {\rm{C}}\limits^\_

Answer

${\left( {{\rm{C}}{{\rm{H}}_3}} \right)_2}\mathop {\rm{C}}\limits^\_ {\rm{H}} > \mathop {\rm{C}}\limits^\_ {\rm{C}}{{\rm{l}}_3} > {{\rm{C}}_6}{{\rm{H}}_5}{\rm{C}}{{\rm{H}}_2} > {\left( {{\rm{C}}{{\rm{H}}_3}} \right)_3}\mathop {\rm{C}}\limits^\_ $

Answer

${\left( {{\rm{C}}{{\rm{H}}_3}} \right)_3}\mathop {\rm{C}}\limits^\_ > {\left( {{\rm{C}}{{\rm{H}}_3}} \right)_2}\mathop {\rm{C}}\limits^\_ {\rm{H}} > \mathop {\rm{C}}\limits^\_ {{\rm{H}}_2} > \mathop {\rm{C}}\limits^\_ {\rm{C}}{{\rm{l}}_3}$
