JEE Main Chemistry question

At ordinary temperature and pressure, among the halogens, chlorine is a gas, bromine is a liquid and iodine is a solid. This is because:

(A)The specific heats are in the order
(B)Intermolecular forces among molecules of chlorine are the weakest and those of iodine are the strongestCorrect
(C)The order of density is
(D)The order of stability is

Answer: (B)

Solution

The physical state (gas, liquid or solid) at room temperature is governed by the strength of intermolecular (van der Waals/London dispersion) forces, which increase with increasing
