Question

Nascent oxygen is a powerful ___(i)____ agent and this is responsible for bleaching property of ___(ii)____.

• A. (i) - reducing, (ii) - sulphur
• B. (i) - oxidising, (ii) - sulphur
• C. (i) - reducing, (ii) - chlorine
• D. (i) - oxidising, (ii) - chlorine

Answer 1

The correct option is D (i) - oxidising, (ii) - chlorine

Hypochlorous acid $\left(HOCl\right)$ is formed when chlorine gas is dissolved in water. This hypochlorous acid releases nascent oxygen $\left[O\right]$, and gets converted into hydrochloric acid. Nascent oxygen is a powerful oxidising agent and this is responsible for bleaching property of chlorine.
