Q.
        Chlorine reacts with hot and concentrated NaOH and produces compounds (X) and (Y). Compound (X) gives white precipitate with silver nitrate solution. The average bond order between Cl and O atoms in (Y) is _________. 
Given 3
      Solution:
Bond order of Cl-O Bond=$1+\frac{2}{3}=\frac{5}{3}$ 
$=1.66 \,or\ 1.67$
