The p-Block Elements
Question
Wired Faculty App

Write the reactions of F2 and Cl2 with water.

Answer

Fluorine reacts violently with water forming hydrogen fluoride, and liberates oxygen which is highly charged with ozone.
(i) 2F2(g) + 2H2O(l) → 4H+ (aq) + 4F–(aq) + O2(g)

Chlorine dissolves in water to some extent to give a green solution

(ii) Cl2+ H2O →  HCI + HOCl
