Rank the Following Radicals in Order of Decreasing Stability, Putting $\mathrm { CH } _ { 3 } \dot { \mathrm { C } } \mathrm { H } _ { 2 }\quad$

Multiple Choice

Rank the following radicals in order of decreasing stability, putting the most stable first. $\mathrm { CH } _ { 3 } \dot { \mathrm { C } } \mathrm { H } _ { 2 }\quad$ $\mathrm { H } _ { 2 } \mathrm { C } = \mathrm { C } \dot { \mathrm { C } } \mathrm { H } _ { 2 }\quad$ $\mathrm { CH } _ { 3 } \dot { \mathrm { C } } \mathrm { HCH } _ { 3 }\quad$ $\left( \mathrm { CH } _ { 3 } \right) _ { 3 } \dot { \mathrm { C } }$
I $\quad\quad\quad\quad\quad\quad\quad$ II $\quad\quad\quad\quad\quad\quad\quad$ III $\quad\quad\quad\quad\quad$ IV

A) II > IV > III > I
B) III > II > IV > I
C) IV > III > II > I
D) IV > III > I > II
