Chemistry - CHEMICAL BONDING Question with Solution | TestHub

Option A is incorrect because NH₃ is a much stronger Lewis base than AsH₃ due to Nitrogen's smaller atomic size and higher electron density.

Option B is correct because less electronegative chlorine atoms leave higher electron density on nitrogen compared to highly electronegative fluorine atoms.

Option C is correct because symmetrical cleavage of B₂H₆ by CH₃OCH₃ forms BH₃ ⋅ O(CH₃)₂, where Boron retains its sp³ hybridization.

Option D is incorrect because according to Drago's rule, even though SbH₃ forms bonds using almost pure p-orbitals without hybridization, the molecule stably exists.
