Question

A compound X consists of one molecules. Hence X will have:

• A. A crystalline hard structure
• B. A low melting point and boiling point
• C. an ionic bond
• D. a strong force of attraction between its molecule

Answer 1

The correct option is B

A low melting point and boiling point

Explanation:

• The compound X is made up of a molecule. So, the compound is a covalent compound.
• Covalent compounds are those compounds that are formed by one or more than one covalent bond.
• Covalent bonds are those bonds that are formed by mutual sharing of electrons between the atoms have similar electronegativities or have small differences in electronegativity.
• In the covalent compounds, the intermolecular forces are of varied nature and are usually weak and can be easily overcome by applying a small amount of heat.
• Hence, compound X has a low melting and boiling points.

Therefore, option (B) is correct.
