Question

1.Why does the basic character of hydroxides of alkali metals increase down the

group?​

Answer 1

Answer:Basic Strength of Alkali Metal Hydroxides As we move down the group Li to Cs, the basic strength of these hydroxides increases. Due to their low ionization energies, the hydroxides of alkali metals act as strong bases that decrease down the group.

Answer 2

Answer:

The hydroxides are basic in nature and basic strength increases down the group. This is due to the low ionization energies of these metals where the M-O bond in MOH is weak and it can cleave to give OH- ions in solution. As the ionization energy decreases down the group, the basic strength of the hydroxides increases.
