Question

In radical chlorination of alkanes, non-equivalent hydrogens react with chlorine atoms at different rates. At 35

Answer 1

1) Specify the most reactive C-H bond(s), a-c.

The Answer is b, the tertiary center, because the radical formation at this center is stbilised by the three alkyl groups through inductive effect and hyper-conjugation.

Two non-equivalent C-H bonds of comparable reactivity should be separated by commas, i.e. a,c.

b > c > a

2) Specify the site of chlorination in the major monochloro substitution product, a-c.
Two products that form in comparable quantities should be separated by commas, i.e. a,c

Again the answer is b, the tertiary center, because the radical formation at this center is stbilised by the three alkyl groups through inductive effect and hyper-conjugation.

b > c > a

1) Specify the most reactive C-H bond(s), a-c.

The answer is b becuse it is tertiary center and produced more stable tertiary-radical
Two non-equivalent C-H bonds of comparable reactivity should be separated by commas, i.e. a,c.
b > a

2) Specify the site of chlorination in the major monochloro substitution product, a-c.

The anser is b, the tertiary center.

Two products that form in comparable quantities should be separated by commas, i.e. a,c

b > a
