An Intiative by Sri Chaitanya

Among the addition compounds formed by NO with halogens, $F N O, C l N O$ and $B r N O$ , the $N - O$ bond length is shortest in FNO and longest in BrNO

Among the $F N O, C l N O$ and $B r N O$ the bond angle is lowest in $F N O$ and largest in $B r N O$

Some metals are found in nature as their oxides whereas others (heavier metals such as lead mercury etc.) are found as sulphides

The bond angles in $H_{2} O, H O F$ and $O F_{2}$ are in the order $H_{2} O > O F_{2} > H O F$

answer is A, B, C, D.

Detailed Solution

A) Electron affinity of oxygen is least among the oxygen family elements and thus its formation $O^{- 2}$ is more endothermic
B) $S F_{6}$ is non-polar while in $S F_{4}$ is polar
C) Due to steric hindrance $S F_{6}$ is chemically inert
D) $S O C l_{2}$ is the chloro derivatives of $H_{2} S O_{3}$ while $S O_{2} C l_{2}$ is the chloro derivative of $H_{2} S O_{4}$
