Question

Which saturated hydrocarbon has the molecular formula \(\mathrm{C_3H_6}\)?

This question was previously asked in
RRB Group D 2025 Question Paper (18-Aug-2026) (Shift 1)
The correct answer is

Cyclopropane

Cyclopropane (\(\mathrm{C_3H_6}\)) is a saturated cyclic hydrocarbon - each carbon has only single bonds, with the ring structure accounting for the formula normally associated with alkenes.

Propane is \(\mathrm{C_3H_8}\), propene is \(\mathrm{C_3H_6}\) but unsaturated (has a C=C double bond), and propyne is \(\mathrm{C_3H_4}\).

Hence, this is the correct answer.(Cyclopropane) is correct.
