Question

# The most stable free radical among the following:

A
C6H5CH2CH2
B
C6H5CHCl3
C
CH3CH2
D
CH3CHCH3

Solution

## The correct option is A $${ C }_{ 6 }{ H }_{ 5 }{ CH }_{ 2 }\overset { \bullet }{ C } { H }_{ 2 }$$Free radical stability is similar to that of carbocation so 3°>2°>1° and electron releasing group increase stability while election withdrawing decrease the stability, also resonance increase stability that's why option A is correct. Chemistry
