This is a multiple choice answer as classified in NCERT Exemplar
The Correct Answer is Option (i).
Alkyl halides have a higher density than water. Their densities are determined by the masses of the halogen atoms, the number of halogen atoms, and the number of carbon atoms. Simply expressed, Br has an atomic mass of 79 while Cl has an atomic mass of 35. (d) will be the heaviest of the molecules, followed by (c), (b), and (a). Because density is exactly proportional to mass, the order of decreasing densities will be the same. The right answer is (i).
