Question
  1. Name three group of d-block elements which do not form hydride.
  2. What happens when hypchlorous acid reacts with $\mathrm{H}_2 \mathrm{O}_2$?
✓

Answer

  1. Group 7, 8, 9 do not form hydride.
  2. $\text{H}_2\text{O}_2+\text{HOCl}\xrightarrow{\ \ \ \ \ \ }\text{HCl}+\text{H}_2\text{O}+\text{O}_2$
$\text{HCl},\text{O}_2$ and $\text{H}_2\text{O}$ are formed. $\text{HOCl}$ acts as oxidising

agent.
