Answer: Sample C is a covalent compound.
Step-by-step explanation:
A covalent compound is a compound formed by the sharing of electrons.
Properties of a covalent compound are as follows.
- They have low melting and boiling point as they have weak intermolecular forces which can be easily broken down at low temperature.
- Covalent compounds do not conduct electricity.
- Covalent compounds do not dissolve easily.
- Due to weak intermolecular forces, a covalent compound can be easily broken down as compared to an ionic compound.
Out of the give samples, only sample C represents property of a covalent compound as Sample C is a liquid that evaporates at room temperature.
Thus, we can conclude that sample C is a covalent compound.
