Question
Chapter 12, Problem 44P
Interpretation Introduction
Interpretation:
The value for the relative east of removing a hydrogen atom from tertiary, secondary and primary hydrogen carbons by a chlorine radical has to be given.
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.

A chemist wanted to determine experimentally the relative ease of removing a hydrogen atom from a tertiary, a secondary, and a primary carbon by a chlorine radical. He allowed 2-methylbutane to undergo chlorination at 300 °C and obtained as products 36% 1-chloro-2-methylbutane, 18% 2-chloro-2-methylbutane, 28% 2-chloro-3-methylbutane, and 18% 1-chloro-3-methylbutane. What values did he obtain for the relative ease of removing a hydrogen atom from tertiary, secondary, and primary hydrogen carbons by a chlorine radical under the conditions of his experiment?
Radical Mono-Chlorination of pentane is a poor way to prepare 1-chloropentane, but radical
chlorination of neopentane, (CH3)4C, is a good way to prepare neopentyl chloride. Write an
equation for both of these reactions and explain why this is.
Pentane
Neopentane
2-chloropropane is a major product of the reaction of chlorine with propane under ultraviolet light. Write the mechanism for this reaction including the initiation step and the two propagation steps.
