a. How does basic character of oxides and hydroxides vary down the group in alkali metals? Why?
b. How does reducing power of elements vary in group `1`?

Text Solution

Verified by Experts

a. It goes on increasing down the group due to decrease in ionisation energy and increase in metallic character.
b. Reducing power of `Li` is highest, `Na` is lowest, then it goes on increasing :`LigtCsgtRbgtKgtNa`.
