Medium INTEGER +4 / -1 PYQ · JEE Mains 2020

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 CI and O atoms in (Y) is.

Answer (integer) 1

Solution

3Cl<sub>2</sub> + 6NaOH $\to$ 5NaCl + NaClO<sub>3</sub> + 3H<sub>2</sub>O <br><br>NaCl + AgNO<sub>3</sub> $\to$ AgCl<sup>-</sup> $\downarrow$ + NaNO<sub>3</sub> <br><br>$\therefore$ X = NaCl then Y = NaClO<sub>3</sub> <br><br>Here in anion ClO<sub>3</sub><sup>-</sup> has bond between Cl and O atom. <br><br>Bond order of Cl–O Bond = <span style="display: inline-block;vertical-align: middle;"> <div style="text-align: center;border-bottom: 1px solid black;">Total bond</div> <div style="text-align: center;">Total resonating structure</div> </span>. <br><br>= ${5 \over 3}$ = 1.67
