Among the following, the correctly matched pair is
- A electron deficient hydride \(-\mathrm{SiH}_4\)
- B saline hydride - \(\mathrm{CrH}\)
- C electron precise hydride - HF
- D electron rich hydride \(-\mathrm{NH}_3\)
Answer & Solution
Correct Answer
(D) electron rich hydride \(-\mathrm{NH}_3\)
Step-by-step Solution
Detailed explanation
\(\mathrm{NH}_3\) is an electron-rich hydride as \(\mathrm{N}\)-atom belongs to group - 15 and uses three of its valence electrons to make three \(\mathrm{N}-\mathrm{H}\) bonds and the remaining two electrons form a lone pair.
