Q. Which of the given is a covalent compound -
✅ Correct Answer: (B)
Carbon tetrachloride
Explanation: A covalent compound is formed when atoms share electrons to achieve a stable electron configuration. These compounds typically involve non-metals and have strong covalent bonds.
Why Carbon Tetrachloride (CCl₄) is Covalent?
Carbon (C) and Chlorine (Cl) are both non-metals.
They form bonds by sharing electrons rather than transferring them.
The bond between Carbon and Chlorine is covalent.
Other Options Explained:
(A) Sodium chloride (NaCl) → Ionic, as it is formed by the transfer of electrons from Na (metal) to Cl (non-metal).
(C) Magnesium fluoride (MgF₂) → Ionic, as Mg (metal) donates electrons to F (non-metal).
(D) Calcium chloride (CaCl₂) → Ionic, as Ca (metal) transfers electrons to Cl (non-metal).
Thus, the correct answer is (B) Carbon tetrachloride (CCl₄), as it is a covalent compound.
