Vedclass · Accepted Answer

In the hydrides of group-$15$ of the periodic table,the stability increases from $NH_3$ to $BiH_3$.

Vedclass · Answer

(A) $1$. The stability of group-$15$ hydrides decreases from $NH_3$ to $BiH_3$ because the bond dissociation energy decreases as the size of the central atom increases. Thus,the statement in option $A$ is incorrect.$2$. Nitrogen can form $p\pi - p\pi$ multiple bonds but cannot form $d\pi - p\pi$ bonds due to the absence of $d$-orbitals. However,the statement in option $B$ is technically ambiguous as it implies nitrogen cannot form $d\pi - p\pi$ bonds,which is true,but option $A$ is factually incorrect regarding stability trends.$3$. Due to high inter-electronic repulsion of the non-bonding electrons,the $N-N$ single bond is weaker than the $P-P$ single bond.$4$. $N_2O_4$ exhibits resonance,and the statement is generally accepted in the context of its structure.
