Amongst the halogens F 2 , CI 2 , Br 2 , I 2 the correct arrangement on the basis of increasing melting point is
Options
- AF 2 < CI 2 < Br 2 < I 2
- BI 2 < Br 2 < CI 2 < F 2
- CI 2 < F 2 < CI 2 < Br 2
- DF 2 < Br 2 < CI 2 < I 2
Correct answer
A. F 2 < CI 2 < Br 2 < I 2
Step-by-step solution
Halogens in solid state are molecular crystals, held by vanderwaal's forces & their melting point increases down the group due to increase in size.
