Which of the following is Hypochlorous acid?
Correct answer: A. HCIO
- A. HCIO
- B. HCIO2
- C. HCIO3
- D. HCIO4
Explanation
a) HCIO (Hypochlorous acid):This is the correct option. Hypochlorous acid (HCIO) is a weak acid with the chemical formula HClO. It is formed when chlorine gas (Cl2) dissolves in water, and it is the active component responsible for the disinfectant properties of chlorine-containing solutions, such as bleach.

About Periodic Properties and Trends
Periodic properties arise from electron configuration and effective nuclear charge, producing trends in atomic and ionic radius, ionization energy, electron affinity, electronegativity, metallic character and reactivity. Comparisons run across periods and down groups, with attention to common exceptions. The topic also relates these trends to the behavior of s-block and p-block elements.
