Which from following properties is exhibited by group 2 elements?
- A Act as inert elements in +1 state.
- B Form \(\mathrm{MH}_2\) type hydrides with hydrogen on heating.
- C Elements at the top in the group catch fire when kept on water.
- D Reducing power of these elements is more than group I elements.
Answer & Solution
Correct Answer
(B) Form \(\mathrm{MH}_2\) type hydrides with hydrogen on heating.
Step-by-step Solution
Detailed explanation
All the metals of group 2, except beryllium, when heated with hydrogen form \(\mathrm{MH}_2\) type hydrides. Hence, statement (B) is correct.
Elements of group 2 elements act as inert elements in +2 state. Elements at the top in the group 2 do not catch fire when kept on water. Reducing power of group 2 elements is less than group 1 elements. Hence, statements (A), (C) and (D) are incorrect.
