Question
The starting material is used to prepare hydrocarbons like methane is
(i) Charcoal
(ii) Hydrogen
(iii) Carbon dioxide
(iv) Carbon monoxide
- Only (i) and (ii)
- Only (i) and (iii)
- Only (ii) and (iii)
- Only (ii) and (iv)
Hint:
It can be prepared by distilling an allotrope of carbon in the presence of hydrogen and carbon.
The correct answer is: Only (i) and (ii)
The correct option is a)Only (i) and (ii).
- Methane is commercially synthesized by distilling bituminous coal and heating a mixture of carbon and hydrogen.
- It can be made in the laboratory by heating sodium acetate and sodium hydroxide and reacting aluminum carbide (Al4C3) with water.
So the starting products are coal and hydrogen.

Sugar charcoal can also be prepared by the following.
The correct option is d)By dehydration of cane sugar.
Sugar charcoal is made by destructive distillation of sugar cane sugar. It is also made by dehydrating sugar in the presence of concentrated sulfuric acid. Sulfuric acid is a dehydrating agent, so it absorbs water from the sugar, leaving behind a black carbon residue.
