The type of bonding present in the hydrogen chloride molecule:
- Ionic bond
- Double covalent bond
- Polar covalent bond
- Triple covalent bond
Answer
Polar covalent bond
Reason — Hydrogen chloride is formed by the sharing of one pair of electrons between hydrogen and chlorine, so the bond is covalent. Because chlorine is much more electronegative than hydrogen, the shared electron pair is pulled closer to chlorine, producing a partial negative charge (δ–) on chlorine and a partial positive charge (δ+) on hydrogen. This unequal sharing of electrons leads to the formation of a polar covalent bond.
