Question

Which of the following property is not shown by covalent compounds?

• A. Low boiling points and melting points
• B. Poor Conductors of Heat and Electricity
• C. The movement of the covalent bond is restricted
• D. Brittle Solid

Answer 1

The correct option is C

The movement of the covalent bond is restricted

Explanation for correct option:

C. The movement of the covalent bond is restricted

Covalent compounds:

• “A covalent compound is formed when there exists a covalent bond between a molecule.”
• These compounds share one or more pairs of valence electrons.
• When two non-metals react with each other, they result in the formation of a covalent compound and they are electrically neutral.

The property that is not shown by the covalent compound is the movement of covalent molecules is restricted as the covalent molecules move freely and tend to exist as gases/liquids/soft liquids at room temperature.

Explanation for incorrect options:

Properties of covalent compound:

• The melting and boiling points of covalent compounds are very low due to weak interactions.
• Covalent compounds do not conduct electricity as well as heat.
• The covalent compounds are insoluble in water.
• They are brittle solid.

Thus, options A, B, and D are incorrect.

Hence, the correct option is C i.e. the movement of the covalent bond is restricted.
