What products are formed when the mixture of `CH_(4) and Cl_(2)` is exposed to direct sunlight?

A

`C Cl_(4)+4HCl`

B

`CHCl_(3)+3HCl`

C

`CH_(2)Cl_(2)+2HCl`

D

`C+4HCl`

Text Solution

Verified by Experts

The correct Answer is:
D
Chlorine has no action on methane in the dark. In bright sunlight ( Providing more photons), the reaction is explosive. Hydrogen chloride and carbon are formed:
`CH_(4)+2Cl_(2)rarrC+4HCl`
If diffused sunlight, no explosion occurs, but a series of substitution reactions take place whereby four `H` atoms in `CH_(4)` are successively replaced by `Cl` atoms.
