Answer & Solution
Correct Answer
(C) I, II, IV
Step-by-step Solution
Detailed explanation
(I) \(\mathrm{B}_2 \mathrm{H}_6\) (diborane) is an electron deficient hydride. This can be explained on the basis of structure given below. \(3 \mathrm{C}-2 e^{-}\)electron deficient bridge bond (II) \(\mathrm{NH}_3\) is electron rich hydride due to presence of lone pair of…
