Which property is most affected if the length of the carbon chain in an alkane increases?
Boiling point
In alkanes, a longer carbon chain means a larger molecule with stronger intermolecular forces between molecules.
More energy is needed to separate the molecules, so the boiling point rises steadily along the series (methane is a gas, octane a liquid).
Alkanes remain colourless and non-conducting, and all are flammable.
Hence, the answer is boiling point.
