What is the boiling point of butanol?

The boiling point of butanol is 117.7°C. This compound, a four-carbon alcohol with the molecular formula C4H10O, exhibits specific physical properties due to its molecular structure. Butanol has a moderate boiling point when compared to other small alcohols, which can often be attributed to the presence of hydrogen bonding between molecules. As the number of carbon atoms increases in alcohols, their boiling points typically rise due to increased molecular weight and the strength of intermolecular forces.

In contrast, other options listed either fall significantly lower or higher than the established boiling point of butanol. The boiling points of different alcohols can vary widely based on their structural features, such as branching or the presence of additional functional groups, but for butanol specifically, 117.7°C is well-documented in chemical literature as its boiling point. This characteristic is crucial for various applications in organic chemistry and industrial processes.
