Question
  1. How does basic character of oxides and hydroxides down the group in alkali metals change? Why?
  2. How does reducing power of elements vary in Group I?
✓

Answer

  1. It goes on increasing down the group due to decrease in ionisation energy and increase in metallic character.
  2. Reducing power of 'Li' is highest, Na is lowest, then it goes on increasing:
Li > Cs > Rb > K > Na.
