The boiling point of butanol (CH3CH2CH2CH2OH) is predicted to be  

> 97°C and < 137°C

Why boiling point of butanol is higher than boiling points of propanol?

Because propanol is bigger and has more London Dispersion Forces, the intermolecular forces are stronger and it takes more energy to separate the molecules. Propanol also has higher mass, thus moving it around and separating it also demands more energy. Both of these will result in propanol having a higher boiling point.

Why boiling point of butanol is less than boiling points of pentanol?

The boiling point of an alcohol is always significantly higher than that of the analogous alkane. Pentanol has higher mass and more London dispersion forces than butanol. These two factors determine the boiling point of alkane. Thus, butanol demands less energy than pentanol to separate the molecules.

So, the boiling point of butanol lies between the boiling points of propanol and pentanol that is > 97°C and < 137°C.
