Vedclass · Answer

(C) $1$. Thermal stability of hydrogen halides decreases down the group due to the increase in bond length and decrease in bond dissociation enthalpy: $HF > HCl > HBr > HI$. Thus,$HF > HCl > HBr$ is correct.$2$. Lewis basic character of phosphorus trihalides: The electronegativity of the halogen decreases from $F$ to $Br$,which increases the availability of the lone pair on phosphorus. Thus,$PF_3 $3$. $\%\, p-$character: In $NO_2^+$ ($sp$ hybridization,$50\%\, p-$character),$NO_3^-$ ($sp^2$ hybridization,$66.6\%\, p-$character),and $NH_4^+$ ($sp^3$ hybridization,$75\%\, p-$character). The correct order is $NO_2^+  NO_3^- > NH_4^+$ is incorrect.$4$. Bond angle: In hydrides of group $15$,the bond angle decreases as the electronegativity of the central atom decreases: $NH_3 > PH_3 > AsH_3$. This is correct.
