प्रश्न
Which of the following is a common characteristic of a covalent compound?
पर्याय
High melting point
Consists of molecules
Always soluble in water
Conducts electricity when it is in the molten state
उत्तर
Consists of molecules
Explanation:
- A covalent compound is formed by sharing of electrons between the atoms of the same element of a different element.
- Thus, the joining of different atoms forms a molecule. e.g.- N2, H2, H2O etc.
- That means the constituent particles of covalent compounds are molecules.
