Interpretation:
The properties of a substance that definitely establish that it is a molecular material are to be stated.
Concept introduction:
Substances are classified on the basis of the kinds of bonding present in it. There are three types of substances.
- Ionic substances
- Molecular substances
- Metallic substances
Molecular substances have covalent bonds between the atoms, ionic substances have electrostatic forces between the ions, and metallic substances have metallic bonds.
Answer to Problem 1ASA
Molecular substances are formed by the sharing of the electrons. They are volatile in nature, and do not conduct electricity either in solid or in the molten state.
Explanation of Solution
The properties of a substance that is molecular material are listed below.
- Molecular substances are formed by the sharing of the electron (covalent bond) between the atoms.
- Molecular substances are liquid at room temperature.
- Molecular substances are volatile in nature.
- Molecular substances do not conduct electricity either in solid or in the molten state.
- Molecular substances are soluble in a few organic solvents.
- Some molecular substances are polar in nature and they all are soluble in water.
Molecular are liquid at room temperature, volatile in nature, and do not conduct electricity either in solid or in the molten state. A few molecular substances are polar in nature.

- Read the descriptions below of two substances and an experiment on each. Decide whether the result of the experiment tells you the substance is a pure substance or a mixture, if you can. • Sample A is 100. g of a coarse grey powder with a faint unpleasant smell. 15. mg of the powder are put into a very thin tube and heated. The powder begins melting at 66.2 °C. The temperature continues to rise as the powder slowly melts, and the last of the powder becomes liquid at 76.0 °C. Sample B is a solid yellow cube with a total mass of 50.0 g. The cube is put into a beaker filled with 250. mL of water. The cube collapses into a small pile of orange powder at the bottom of the beaker. When this powder is filtered out, dried and weighed, it has a total mass of 29.9 g. If the experiment is repeated with 500. mL of water, the powder that's left over has a mass of 30.0 g. Is sample A made from a pure substance or a mixture?
