Question

Melting point of A , B , C , D are 299k , 111k , ,150k , inter particles forces of attraction are in order.Arrange the substances A, B, C, D in order of increasing inter-particle forces of attraction based on their melting points:

Answer 1

The order of substances A, B, C, D in increasing inter-particle forces of attraction based on their melting points is B, C, D, A.

Step-by-step explanation:

The melting point of a substance is influenced by the strength of the attractive forces between its particles. Molecules with weak attractive forces have low melting points, while those with stronger attractive forces have higher melting points. Based on the given information, we can arrange substances A, B, C, D in order of increasing inter-particle forces of attraction:

1. Substance B (melting point = 111 K)
2. Substance C (melting point = 150 K)
3. Substance D (melting point = 299 K)
4. Substance A (melting point = 299 K)

Therefore, the correct order of increasing inter-particle forces of attraction is B, C, D, A.
