QJEEM20Cha223: JEE Main 2020 Chemistry - Class 11 JEEM20Cha223 Solution: Chlorine reacts with hot and concentrated NaOH and produces…

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.

Step-by-Step Verified Solution

3Cl2 + 6NaOH →\to 5NaCl + NaClO3 + 3H2O

NaCl + AgNO3 →\to AgCl- ↓\downarrow + NaNO3

∴\therefore X = NaCl then Y = NaClO3

Here in anion ClO3- has bond between Cl and O atom.

Bond order of Cl–O Bond =
Total bond
Total resonating structure
.

= 53{5 \over 3} = 1.67
