Step-by-Step Verified Solution
Steric congestion around the carbon atom undergoing the inversion process will slow down the reaction, hence less congestion faster will the reaction. So, the order is
C{H_3}Cl > \left( {C{H_3}} \right)C{H_2} - Cl >
\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,{\left( {C{H_3}} \right)_2}CH - Cl > {\left( {C{H_3}} \right)_3}CCl
C{H_3}Cl > \left( {C{H_3}} \right)C{H_2} - Cl >
\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,{\left( {C{H_3}} \right)_2}CH - Cl > {\left( {C{H_3}} \right)_3}CCl
