When Cl2 gas reacts with hot and concentrated sodium hydroxide solution, the oxidation number of chlorine changes from
Detailed Solution for Test: p-Block Elements - 2 - Question 10

The correct answer is option D
The reaction of chlorine gas with hot and concentrated sodium hydroxide solution is
3Cl2​ + 6NaOH⟶NaClO3​+ 5NaCl+3H2​O
Oxidation number of Cl is 0 in Cl2​, −1 in NaCl and +5 in NaClO3​
So the oxidation number of chlorine changes from Zero to -1 and Zero to +5.
