Question

Chlorine forms the most acidic oxide amoung the 3 period of element

Answer 1

Reasons:

• Highest oxide of chlorine.
• Maximum oxidation state of chlorine is +7.
• Chlorine oxide with water gives perchloric acid.
• Chlorate ion is formed when an hydrogen atom is lost.
• De-localization of charge over every oxygen atom makes it very stable

Hence, Chloric acid is stable and highly reactive making it very strong.
