Question

Due to __________________ between alcohol molecules, their boiling point is _______________ than observed for hydrocarbon molecules of similar molecular size. Alcohols are __________________ as they contain both hydrophobic and hydrophilic regions. As the molecular weight of alcohols increases, water solubility _____________ due to the relatively higher hydrophobic content.

Answer 1

Ans :

The alcohols are the molecules that have hydroxyl group (OH) attached to the hydrocarbon chain. The OH group is polar and the hydrocarbon chain is nonpolar.

So here :

Due to hydrogen bonding between alcohol molecules , their boiling point is more than observed for hydrocarbon molecules of similar molecular size. Alcohols are amphiphilic as they contain both hydrophobic and hydrophilic regions. As the molecular weight of alcohols increases, water solubility decreases due to the relatively higher hydrophobic content.
