Which of the following initiates the chlorination of `CH_(4)` in the dark at `150^(@)C` ?

A

`PbCO_(3)`

B

`O_(2)`

C

Hydroquinone

D

`Pb(C_(2)H_(5))_(4)`

Verified by Experts

The correct Answer is:
D
Tetraethyl lead, `Pb(C_(2)H_(5))_(4)`, undergoes thermal homolysis of the `C-Pb` bound at `150^(@)C`. Ethyl radical, `CH_(3)CF_(2)`, then generates `Cl` which initiates the propagation steps
