Question

Which among the following are unsaturated hydrocarbons?

• A. (i) and (ii)
• B. (ii) and (iii)
• C. (iii) and (iv)
• D. (ii) and (iv)

Answer 1

The correct option is D (ii) and (iv)

Hydrocarbon carrying double and triple bonds in its molecule makes it an unsaturated hydrocarbon. Alkanes are saturated hydrocarbon while both alkenes and alkynes are unsaturated hydrocarbons.

Hence (ii) and (iv) are unsaturated hydrocarbons.
