Question

Which of the following does not contain any coordinate
bond?
(a) H₃O⁺ (b) BF₄⁻
(c) HF₂⁻ (d) SO₂⁻

Answer 1

HF₂⁻doesn't have the coordinate bonding.

Explanation:

• Coordinate bond is formed when lone pari of an atom is donated to an elecrophile atom.

• This bond mimics a normal covalent bond, but the electron here is donated by only one of the participating atom.

• In H₃O⁺, one coordinate bond is found between the oxygen and a Proton where the lone pair of electron of oxygen is donated to Proton to form a coordinate bond.

• In BF₄⁻, lone pair of fluoride ion is donated in the vacant orbital of boron to form a coordinate bond.

• In SO₂⁻, coordinate bond is formed between the oxygen and sulphur is formed.

• But in HF₂⁻, the bond between the hydrogen of hydrogen fluoride and a fluoride is hydrogen bond.

• So no coordinate bond is formed in HF₂⁻.
