[Review Topics] In radical chlorination of alkanes, non-equivalent hydrogens react with chlorine atoms at different rates.

Explanation / Answer

1. You are right, site b is correct since it forms more stable secondary freeradical while a and c forms primary freeradical.

Stability of radical :3°>2°>1°

2. Site a gives major yield since it has 9 hydrogens, 9x 1 = 9 times = 9 x 100/19.8=45.4%

b site has only 2 hydrogene, 2x3.9=7.8 =7.8x100/19.8=39%

While c has 3 hydrogens, 3x1= 3x100/19.8=15%
