Vedclass · Answer

(C) $1$. $NCl_3$ undergoes hydrolysis to give $NH_3$ and $HOCl$ $(NCl_3 + 3H_2O \rightarrow NH_3 + 3HOCl)$. This statement is true.$2$. $PH_3$ is less stable than $NH_3$ because the $P-H$ bond is weaker than the $N-H$ bond due to the larger size of the $P$ atom. This statement is true.$3$. $PH_3$ is a much stronger reducing agent than $NH_3$ because the $P-H$ bond is easily broken,allowing it to release hydrogen. Therefore,the statement that $PH_3$ is a weaker reducing agent is false.$4$. In the solid state,$NO$ exists as a dimer $(N_2O_2)$,which is diamagnetic because all electrons are paired. This statement is true.
