A covalent bond in which the electrons are shared unequally is called:
AA pure covalent bond
BAn ionic lattice bond
CA metallic alloy bond
DA polar covalent bond
Answer & Solution
Correct answer: D. A polar covalent bond
1. If the atoms that form a covalent bond are identical, the electrons must be shared equally.
2. When the atoms differ, one pulls the shared pair harder than the other.
3. This unequal distribution of electrons is known as a polar covalent bond.
4. It is characterised by a partial positive charge on one atom and a partial negative charge on the other.
