Question

Q. Which of the following is the weakest base?
A \(\mathrm{Ca}(\mathrm{OH})_{2}\)
в \(\mathrm{KOH}\)
(c) \(\mathrm{Li}(\mathrm{OH})\)
D \(S r(O H)_{2}\)

Answer 1

Solution:
Basic character of hydroxides of s-block elements increase with increasing atomic number. However alkaline earth metal hydroxides are less basic than alkali metal hydroxides. Therefore, \(L i(O H)\) is the weakest base.
