MCQ

Which of the following statement $(s)$ is/are not correct?

A
Alkanes are non polar in nature.
B
Alkanes are soluble in non $-$ polar solvents.
✓
Straight chain alkanes have lesser boiling point than corresponding branched chain isomers.
D
Alkanes exhibit alternations in melting point.

✓

Answer

Correct option: C.

Straight chain alkanes have lesser boiling point than corresponding branched chain isomers.

Alkanes are made of $C$ and $H$ only, so, they are non polar in nature and also due to non polar nature they dissolved in non polar solvent only.
Branched alkanes have lower boiling point than straight $-$ chain alkanes.
Melting point increases with increase in mass.
