Question

With increase in the number of carbon atoms in alkanes, the physical state changes from.

• A. Solid, Liquid, Gas.
• B. Gas, Liquid, Solid.
• C. Solid, Gas, Liquid.
• D. Gas, Solid, Liquid.

Answer 1

The correct option is B Gas, Liquid, Solid.

Physical state of alkane:-
1. Alkane of carbon $C_{1}to{C}_4$ are gases.
2. Alkane of carbon $C_{5}to{C}_{17}$ are liquids.
3. Alkanes having carbon atoms more than 17 are solids.
