CBSE Class 11-science Answered

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. For example, Be(OH)2 is amphoteric, Mg(OH)2 is mildly basic while others are strong bases.
