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?
o n - butanol mixes with water.
o water molecules are carried into n - butanol.
o n - butanol molecules surround water molecules.
o n - butanol molecules are attracted to the surface of the water molecules.

Explanation:

When water dissolves into n - butanol (both polar), first, the n - butanol molecules are attracted to the surface of water molecules due to intermolecular forces. The second step is that n - butanol molecules surround water molecules as the dissolution process progresses at the molecular level.

Answer:

n-Butanol molecules surround water molecules.
