Question

Which of the following is Network Solid?

• A. ${\mathrm{I}}_2$
• B. Diamond
• C. Water(Ice)
• D. ${\mathrm{SO}}_2$(solid)

Answer 1

The correct option is B

Diamond

Explanation for correct option:

B. Diamond

• Diamond has a covalent structure in which each carbon atom is bonded to four other carbon atoms via covalent bonds.
• It has the hardest.
• A lot of energy is needed to detach the atoms in a diamond as there is strong covalent bonding due to which the melting, as well as the boiling point of the diamond, is very high.
• Diamond is a network-type covalent solid that is shown below:

Explanation for incorrect options:

A. Iodine is a molecular solid i.e composed of discrete molecules held together by intermolecular forces.

C. Water(ice) is an example of a molecular solid under its freezing point.

D. ${\mathrm{SO}}_2$(solid) is an example of a gas.

Hence, the correct option is B i.e. Diamond is a network solid.
