Answer to Question #118446 in Chemistry for Angelina

Question

Methanol, ethanol, ammonia, and methylamine are soluble in water because

they can form ion-induced dipoles
they can form hydrogen bonds
there are dipole-dipole forces
there are dispersion forces

Answer 1

They can form hydrogen bonds.

All these molecules can form hydrogen bonds with water molecules due via hydrogen atoms attached to oxygen or nitrogen. As these interactions can be distributed equally between two substances, they are soluble in water.
