Answer: HF-dipole- dipole interaction

CH3OH- dipole-dipole interaction

CaCl2- ion-ion interaction

Explanation:

Both CH3OH and HF possess permanent dipoles which interact with water leading to the dissolution of the above named substances. Remember that water also possesses a permanent dipole. Which can interact with the dipoles on other polar molecules. CaCl2 is purely ionic and interacts with water via ion-dipole mechanism.
