Question
Chapter 17, Problem 1ASA
Interpretation Introduction
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.
Expert Solution & Answer
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.
Conclusion
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.
