Question

Melting points of three substances a, b, c are 98 degree Celsius, 43 degrees celsius and 165 ℃ .arrange them in the increasing order of the inter particle force of attraction in each of them . Give reason for your answer

Answer 1

165 have high melting point because the intermolecular force between it's particles is very high... 98 have less molecular force than first and 43 have less molecular force between it's particles
