In which of the following changes there is no change in hybridisation of the central atom?
- A \(\mathrm{C}_2 \mathrm{H}_4 \stackrel{\mathrm{H}_2 / \mathrm{Ni}}{\longrightarrow} \mathrm{C}_2 \mathrm{H}_6\)
- B \(\mathrm{PCl}_5+\mathrm{Cl}^{-} \longrightarrow \mathrm{PCl}_6^{-}\)
- C \(\mathrm{BF}_3+\mathrm{F}^{-} \longrightarrow \mathrm{BF}_4^{-}\)
- D \(\mathrm{NH}_3+\mathrm{H}^{+} \longrightarrow \mathrm{NH}_4^{+}\)
Answer & Solution
Correct Answer
(D) \(\mathrm{NH}_3+\mathrm{H}^{+} \longrightarrow \mathrm{NH}_4^{+}\)
Step-by-step Solution
Detailed explanation
The total number of electron pairs (bond pairs + lone pairs) is the same for \(\mathrm{NH}_3\) and \(\mathrm{NH}_4^{+}\). Thus, their hybridization is also the same that is \(\mathrm{sp}^3\).
