A) reducing agent
B) amphoteric
C) dehydrating agent
D) oxidising agent
Correct Answer: A
Solution :
Alkaline earth metals are reducing agent. Because Reducing nature \[\propto \] tendency to lose electron \[\propto \] electropositive character \[\propto \] atomic size \[\propto \frac{1}{electron\text{ }in\text{ }outermost\text{ }shell}\] In a period from left to right reducing nature decreases because electropositive nature decreases. Alkaline earth metals are good reducing agent but less than alkali metals.
