Question

The melting point of four substances A, B, C and D are 78⁰C, 262⁰C, 100⁰C and 168⁰C. What will

be the increasing order of their interparticle force of attraction?​

Answer 1

Generally,the force of attraction between the particle is proportional to the melting point..

it means more the boiling point more the force of attraction between particles...

so,

the order is

A(78 C) < C(100 C) < D(168 C) <B(262 C)

A have least force of attraction between particle.

and

B have the maximum force of attraction between the particle.
