NEET Hydrocarbons — Set 15

Question 1

What type of bonds are present in unsaturated hydrocarbons?

Accepted Answer

Unsaturated hydrocarbons contain carbon-carbon multiple bonds, specifically double or triple bonds, unlike saturated hydrocarbons with only single bonds.

Question 2

Which hydrocarbon with molecular formula $ \ce{C6H12} $ is a saturated cycloalkane with a six-membered ring?

Accepted Answer

Cyclohexane ($ \ce{C6H12} $) is a saturated cycloalkane with a six-membered ring, fitting $ \ce{C_nH_{2n}} $ for cyclic compounds.

Question 3

Which hydrocarbon is a gas at room temperature?

Accepted Answer

Ethane ($ \ce{C2H6} $), with a boiling point of -89°C, is a gas at room temperature (25°C).
