Solution

The correct option is C

(C2H2)


Step 1:

The compounds containing Carbon (C) atoms have multiple bonds between two Carbon-Carbon (C-C) atoms are called unsaturated hydrocarbons.

The multiple bonds are either double or triple bonds.

Step 2:

The explanation for the correct option:

Alkenes and alkynes contain double and triple bonds between Carbon-Carbon atoms respectively. So these are known as unsaturated hydrocarbons.

The general formula of alkynes is (CnH2n-2).

The first member of the alkyne series is Ethyne (C2H2).

The explanation for the incorrect option:

Methane (CH4) is a saturated hydrocarbon because it contains only a single bond between Carbon and Hydrogen (H) atoms.

Ethene (C2H4) is an unsaturated hydrocarbon because it contains double bonds between two Carbon-Carbon atoms.

Propene (C3H6) is an unsaturated hydrocarbon because it contains double bonds between two Carbon-Carbon atoms.

Final answer:

Hence, option (C) is the correct option.
