Question

Among the given free radical bromination reactions, the reaction(s) in which $3^{\circ }$ halide is a major product is /are :

• A.
• B.
• C.
• D.

Answer 1

Answer: (B), (C), (D)

The correct options are
B
C
D

Stability of halides :
$3^{\circ }>2^{\circ }>1^{\circ }$

In (a) , only $2^{\circ }$ halide is formed as shown :

In (b) , major product that is formed is a $3^{\circ }$ halide as shown :


In (c), major product that is formed is a $3^{\circ }$ halide as shown :



In (d), major product that is formed is a $3^{\circ }$ halide as shown :




$\therefore$ correct options are (b), (c) and (d)
