Current Question (ID: 18004)

Question:

$\text{I. Mg(s)}$ $\text{II. TiO(s)}$ $\text{III. I}_2\text{(s)}$ $\text{IV. H}_2\text{O(s)}$ $\text{The insulator among the given examples is -}$

Options:

1. $\text{Only I}$
2. $\text{Only II}$
3. $\text{III and IV}$
4. $\text{II, III, and IV}$

Solution:

$\text{Molecular solids are insulators.}$ $\text{Iodine is a non-polar molecular solid in which iodine molecules are held together by London force or dispersion force.}$ $\text{This is a soft and non-conductor of electricity.}$ $\text{Water is a hydrogen-bonded molecular solid in which H and O are held together by polar covalent bonds and each water molecule is held together by hydrogen bonding.}$ $\text{Due to non-ionic nature, they are not an electrical conductor.}$
