Question

Identify the ion that contains one lone pair of electrons.

विकल्प

• OH⁻¹

• H₃O⁺

• \[\ce{NH^+_4}\]

• H⁺

Answer 1

H₃O⁺

Explanation:

In OH⁻, the oxygen atom has three lone pairs. In H₃O⁺, the central oxygen forms three single bonds with hydrogen atoms and has one lone pair. In \[\ce{NH^+_4}\], the central nitrogen forms four single bonds with hydrogen atoms, so it has no lone pairs. Finally, H⁺ has no electrons, and therefore it has no lone pairs.
