Question

There are four samples on a laboratory table. Sample A is a hard crystalline solid, which does not break easily. Sample B is a solid that readily dissolves in water. Sample C is a liquid that evaporates at room temperature. Sample D is a colored liquid that conducts electricity. Based on this information, which sample is most likely to be a covalent compound?
A. sample A


B. sample B


C. sample C


D. sample D

Answer 1

according to me it is sample C

Answer 2

Answer: Option (C) is correct.

Explanation:

A covalent compound is formed by the sharing of electrons. The properties of a covalent compound are as follows.

• They are brittle compounds.
• Usually non-polar in nature and do not dissolve in water.
• They have low melting and boiling point.

Also, covalent compounds do not have delocalized electrons so they do not conduct electricity.

Therefore, option C is the correct answer as covalent compounds have low melting and boiling point, hence, sample C is a liquid that evaporates at room temperature.
