Options
- AAlkoxides
- BMetal hydrides
- CPeroxides
- DMetal nitrites
Correct answer
B. Metal hydrides
Step-by-step solution
Alkali metals react with dihydrogen at high temperatures to form the corresponding metal hydrides. 2M + H₂ 2M⁺H⁻ where M represents an alkali metal (Li, Na, K, Rb, Cs). These hydrides are ionic (salt-like) in nature. Answer: Metal hydrides
