Carbon tetrachloride (ccl4) may be produced when reacting excess chlorine with methane in the presence of light. truefalse

False, where does the chlorine come from light anyway?

It is true ... saturated hydrocarbons (alkanes) undergo substitution reactions in which it reacts with chlorine in the presence of sunlight or ultraviolet light to give halogen substituted products known as alkyl halides.

Here, methane reacts with chlorine in the presence of sunlight to produce CCl4.

If u need the equations, I can submit that as well.
