Which from following properties is exhibited by group 2 elements?
Options
- AAct as inert elements in +1 state.
- BForm MH ₂ type hydrides with hydrogen on heating.
- CElements at the top in the group catch fire when kept on water.
- DReducing power of these elements is more than group I elements.
Correct answer
B. Form MH ₂ type hydrides with hydrogen on heating.
Step-by-step solution
All the metals of group 2, except beryllium, when heated with hydrogen form 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.
