Question

Arrange the following on the increasing property given in bracket:
Pentan-1-ol, butan-1-ol, butan-2-ol, ethanol, propan-1-ol, methanol (Boiling Point)

Answer 1

Dear​ Chris,

As the carbon chain increases boiling point increases due to increase in surface area.
In case of same carbon chain but difference in degree of alcohol; in 3^o alcohol the surface area is least (less bp) and maximum for 1⁰ alcohol(high bp).
it means bp is maximum for pentan-1-ol and least for methanol.
Hence the increasing order of bp is methanol<ethanol<propan-1-ol<butan-2-ol<butan-1-ol<pentan-1-ol
