(a) How does hot concentrated sodium hydroxide reacts with chlorine ? Write equation . (b) How does electronegativity of Halogens vary down the group ?

Answer»

Solution : Withhotand ConC NaOH chlorine GIVES chloride and CHLORATE
`6NOH + 3CI _2`to `5NaCl+ NaClO_3 + 3H_2O`
Electronegativity DECREASE down the group . `(F>CL>Br>I)`
