Answer

The compounds can be arranged in the order of increasing melting point as follows:

Step by step solution

01

Melting point

The size of a particular molecule can impact its melting point.Molecules comprising identical melting points may possess a similar structure when compared to those exhibiting varying melting points.

02

Arrangement of compounds based on the increasing order of melting point

The interactions present in 2-propanol are Vander Waals forces, dipole-dipole interaction, and hydrogen bonding. The only interaction that occurs in 2-methylpropane is Vander Waals forces.

Acetone is a ketone, and ketones are regarded as polar compounds. The interaction existing in acetone is dipole-dipole and Vander Waals forces.

The compounds can be arranged in the increasing order of melting points as follows:
