Methane (CH4) forms the molecular solid.
<u>Explanation:</u>
- The molecules which are held together by intermolecular forces are called molecular solids. It is maintained by solids rather than bonds. The force which holds these solids are weaker than other solids.
- It consists of discrete molecules and the cohesive force which binds them together is Vanderwall's force, dipole-dipole interaction and hydrogen bonding. They are held together by an ionic bond or covalent bond.
- The weak intermolecular forces have relatively low melting points which are less than 300 degrees Celsius.
- Organic solvents dissolves Molecular solvents. Many of the molecular solids are soft electrical insulators with low density.

Mole ratio is the ratio between the amount in moles of any two compounds involved in a chemical reaction
3
the mole of Fe3O4 is 1 mole while that of Fe is 3 moles from the reacting equation below
Fe + 4 H2O ----> Fe3O4 + 4 H2
therefore the mole ratio of Fe3O4 to Fe is 1:3(answer A)
