Answer 1

When chlorine gas reacts with hot and

When chlorine gas reacts with hot andconcentrated NaOH solution, it disproportionates

When chlorine gas reacts with hot andconcentrated NaOH solution, it disproportionatesinto chloride () and chlorate () ions.

When chlorine gas reacts with hot andconcentrated NaOH solution, it disproportionatesinto chloride () and chlorate () ions.In this process, oxidation number of chlorine

Answer 2

HELLO DEAR,

ANSWER:-when chlorine gas reacts with hot and concentrated NaOH solution its disproportionate into chloride(Cl-) and chlorate(ClO3-) ions.

I-Cl is more reactive than I2 due to the difference of electronegativity between I and Cl, the bond I-Cl has a slightly ionic nature .This ionic nature causes the bond to be weaker than its counterparts,the covalent bond .

I-Cl is more reactive than I2 due to the ionic nature of I-Cl bond.

I HOPE IT'S HELP YOU DEAR,

THANKS.
