Chapter 12.5, Problem 8P

(a)

Interpretation Introduction

Interpretation:

For problem 7, the major mono chlorination product obtained on disregarding stereoisomers should be given

Concept introduction:

Distribution of products based on Probability and Reactivity:

Depending on the relative rate of alkyl radical formation, the type of chlorination product obtained differs.  At room temperature, it is 5.00 times easier for a chlorine radical to form a tertiary radical than a primary radical, and it is 3.8 times easier to form a secondary radical than a primary radical.  These, ratios differ at different temperatures

(b)

Interpretation Introduction

Interpretation:

The percentage yield of the major product should be calculated.

Concept introduction:

Radical or free radical: unpaired valence electron of an atom, molecule, or ion is called as radical.

chlorine radical forms a tertiary radical five times faster than a primary radical and it forms a secondary radical 3.8 times faster than a primary radical.

Relative rates of alkyl radical formation by a chlorine radical at 125 °C.
