[Review Toples) In radical chlorination of alkanes, non-equivalent hydrogens react with chlorine atoms at different rates. At 35 °C, 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 35 °C.
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 monochldro substitution product, a-c.
Two products that form in comparable quantities should be separated by commas, i. e. a, c
