Which of the following hydroxide of group I is less soluble in water?
Correct answer: B. LiOH
- A. NaOH
- B. LiOH
- C. KOH
- D. RbOH
Explanation
Except lithium hydroxide,all the alkali metal hydroxides are highly soluble in water. LiOH is much less soluble on account of high lattice enthalpy. Therefore, option B is correct.
