Simple Covalent Molecule:

- Contains a atoms.

- Generally and gas at room temperature, but if brittle in nature.

- have van der waal force between molecules.

- have low melting point and .

- do not dissolve in but inorganic solvent.

- do not conduct .

Explanation

Question 4 of 4

1

Covalent (Simple) Molecules have a low melting point and boiling point.

- Simple covalent molecules have covalent bond within the atoms.

- However, they have inter-molecular attraction force, known a Van der Waal force.

- So it requires energy to break the attraction force.

Covalent molecules do not dissolve in water.
- Covalent molecules are mostly .
Water is a .
- Non-polar molecules like H2, Cl2, N2 and CH4 will .
- However some molecules like HCl, NH .
