What is the boiling point of pentanol?

The boiling point of pentanol, a five-carbon alcohol, is accurately determined to be around 82.8°C. Pentanol, specifically 1-pentanol, has a straight-chain structure, which contributes to its physical properties, including boiling point. The relatively low boiling point compared to higher molecular weight alcohols aligns with the trends observed in the alkane and alcohol series, where increasing molecular weight typically correlates with higher boiling points due to augmented van der Waals forces.

Therefore, the choice indicating 82.8°C aligns with known data on the boiling point of pentanol and represents the correct answer, reflecting the compound’s structure and the intermolecular forces at play.
