Vedclass · Answer

(D) The basic strength of metal hydroxides increases down the group due to the increase in ionic character and the size of the metal cation.In a period,the basic strength decreases from left to right as the electronegativity of the metal increases,making the $M-OH$ bond more covalent.$NaOH$ and $KOH$ are strong bases (Group $1$).$Ca(OH)_2$ is a moderately strong base (Group $2$).$Be(OH)_2$ is amphoteric in nature and is the weakest base among the given options because $Be^{2+}$ has a high charge density and small size,making the $Be-OH$ bond highly covalent.

Which of the following is the weakest base among $NaOH$,$Ca(OH)_2$,$KOH$,and $Be(OH)_2$?
