Current Question (ID: 17916)

Question:

$\text{Iodine crystals are classified as-}$ $1. \text{Metallic solids.}$ $2. \text{Ionic solids.}$ $3. \text{Molecular solids.}$ $4. \text{Covalent solids.}$

Options:

1. $\text{Metallic solids.}$
2. $\text{Ionic solids.}$
3. $\text{Molecular solids.}$
4. $\text{Covalent solids.}$

Solution:

$\text{Force of attraction between iodine molecule = London force.}$ $\text{Molecular solids are the substances having molecules as constituent units}$ $\text{having interparticle forces such as Vander Waal's forces or hydrogen bonds.}$ $\text{Iodine crystals are molecular solids because it contains London force as an}$ $\text{intermolecular force.}$
