Question

Water is dissolved into n-butanol (a polar liquid). Which is the second step at the molecular level as water dissolves into n-butanol?

Answer 1

Answer:

Formation of intermolecular hydrogen bonding between water molecules and molecules of n-butanol

Explanation:

Low molecular weight alcohols are miscible with water in all proportions. The reason for this is that, when a low molecular weight alcohol is dissolved in water, intermolecular hydrogen bonds are formed between the low molecular weight alcohol and water molecules.

Low molecular weight alcohols such as n-butanol contain the polar -OH group which interacts with water via hydrogen bonding.
