Question

NH₃ molecule can enter into complex formation through ______.

Options

• ionic bond

• covalent bond

• coordinate bond

• electron-deficient bond

Answer 1

NH₃ molecule can enter into complex formation through coordinate bond.

Explanation:

The NH₃ molecule has a lone pair of electrons on the nitrogen atom, which it can donate to electron-deficient species like metal cations. This donation forms a coordinate bond (also called a dative bond) where both electrons come from NH₃, allowing it to form coordination complexes with transition metals. Hence, NH₃ enters into complex formation through coordinate bonding.
