Which of the following species has tetrahedral geometry?

Options

  1. ABH ₄⁻
  2. BNH ₂⁻
  3. CCO ₃²⁻
  4. DH ₃ O ⁺

Correct answer

A. BH ₄⁻

Step-by-step solution

The central B atom in BH ₄⁻ undergoes s p^3 hybridisation, which results in tetrahedral geometry with 4 bond pairs and 0 lone pairs of electrons.
