$A, B, C$

Vedclass · Answer

(A) $1$. $Bi_2O_5$ is a metallic oxide,which is basic,whereas $N_2O_5$ is a non-metallic oxide,which is acidic. Thus,$Bi_2O_5$ is more basic than $N_2O_5$. Statement $(A)$ is correct.$2$. According to Fajan's rule,smaller cations have higher polarizing power. $N^{3+}$ is much smaller than $Bi^{3+}$,making $NF_3$ more covalent than $BiF_3$. Statement $(B)$ is correct.$3$. $NH_3$ exhibits intermolecular hydrogen bonding,whereas $PH_3$ does not. Therefore,$NH_3$ has a higher boiling point than $PH_3$. Statement $(C)$ is correct.$4$. The $N-N$ single bond is weaker than the $P-P$ single bond due to high inter-electronic repulsion between the lone pairs of nitrogen atoms. Statement $(D)$ is incorrect.

Based on the compounds of group $15$ elements,the correct statement$(s)$ is (are):
$(A)$ $Bi_2O_5$ is more basic than $N_2O_5$
$(B)$ $NF_3$ is more covalent than $BiF_3$
$(C)$ $PH_3$ boils at a lower temperature than $NH_3$
$(D)$ The $N-N$ single bond is stronger than the $P-P$ single bond
