IIn radical chlorination of alkanes, non-equivalent hydrogens react with chlorine atoms at different rates. At 35oC, primary, secondary, and tertiary C-H bonds react at relative rates of 1 : 3.9 : 5.2 respectively. These are conditions of kinetic control where product ratios are determined by relative rates of formation. For example, if A is formed twice as fast as B, the A:B product ratio will be 2. Consider chlorination of the alkane below at 35oC. 1.Specify the most reactive C-H bond(s), a-c.

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

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
