Question

1. The melting point of four substances P, Q, R and S are 0°C ,262°C, 100°C and 168°C. The increasing order of their Interparticle forces of attraction is a) P,R,SQ b) P,Q,S,R c) P,R,Q,S d) P,S,Q,R Wh f


​

Answer 1

Answer:

I think correct answer is a)P, R,S,Q

Explanation:

high melting point means greater force of attraction between particles

C have melting points.

As stronger the faces of attraction between the particles more will be melting point and vice-versa.

Hence,

Order of their inter-particle forces of attraction is B>D>C>A maximum melting point, so maximum inter particles forces of attraction.
