Problem 3P

Each of the following proposed mechanisms for the free-radical chlorination of methane is

wrong. Explain how the experimental evidence disproves each mechanism.

CI2 + hv $\rightarrow{}\$ C ${I}_{2}^{*}$ (an “activated” form of CI2)

C ${I}_{2}^{*}$ + CH4 $\rightarrow{}\$ HCI + CH3CI

CH4 + hv $\rightarrow{}\$ .CH3 + H.

.CH3 + CI2 $\rightarrow{}\$ CH3CI + CI

CI. + H. $\rightarrow{}\$ HCI

Step-by-Step Solution:

Solution 3P:

Here, we are going to describe about the experimental evidence for each mechanism.

Step 1: (a)

It requires only one photon of light to generate CH3Cl. Thus the quantum yield for the reaction is only 1.0.

Quantum yield = $\frac{photon\ emitted}{photon\ absorbed}$

But, in actual, the quantum yield is so high which is more than several hundred. Thus, the high quantum yield indicates about a chain reaction.

Therefore, the above reaction is not a chain reaction. It has no propagation steps.
