Question

Which of the folowing is incorrect?

• A. Nitric oxide depletes ozone layer in upper atmosphere
• B. $O_3$ is a powerful oxidising agent
• C. Acidic strength increases from $H_{2}Te$ to $H_{2}O$
• D. $S{O}_2$ is redusing agent while $Te{O}_2$ is an oxidising agent

Answer 1

The correct option is C Acidic strength increases from $H_{2}Te$ to $H_{2}O$

Acidic strength increases from $H_{2}O$ to $H_{2}Te$ due to decrease in bond dissociation energy down the group.
