Question

Are benzene, sodium bromide, glucose, and pentane more soluble in octane or water, explain why?​

Answer 1

Glucose: more soluble in water. A glucose molecule has six OH groups and these can form hydrogen bonds with the water molecules.

Step-by-step explanation:

Answer 2

Here's what I get

Step-by-step explanation:

Benzene and pentane: more soluble in octane. Both substances are nonpolar, so their molecules can easily intermingle with each other.

Sodium bromide: more soluble in water. The polar water molecules hydrate the ions to form Na⁺(aq) and Cl⁻(aq).

Glucose: more soluble in water. A glucose molecule has six OH groups and these can form hydrogen bonds with the water molecules.
