Expert Solution

Step 1

Note: As per the guidelines solution of 5th question has been made. For the expert solution of remaining questions kindly post the separately.

Answer-5

Melting point of compound depends on the intermolecular attraction forces acting in between the particles. Higher the magnitude of intermolecular attraction forces, higher will be the melting point.
