Which of the following species has tetrahedral geometry?
- A \(\mathrm{BH}_4^{-}\)
- B \(\mathrm{NH}_2^{-}\)
- C \(\mathrm{CO}_3^{2-}\)
- D \(\mathrm{H}_3 \mathrm{O}^{+}\)
Answer & Solution
Correct Answer
(A) \(\mathrm{BH}_4^{-}\)
Step-by-step Solution
Detailed explanation
The central \(B\) atom in \(\mathrm{BH}_4^{-}\)undergoes \(s p^3\) hybridisation, which results in tetrahedral geometry with 4 bond pairs and 0 lone pairs of electrons.
