• # question_answer 73)   All compounds of alkali metals are easily soluble in water but lithium compounds are more soluble in organic solvents. Explain.

The size of $L{{i}^{+}}$ ion is small and thus, it has high polarising power. This brings covalent character in lithium compounds. For example, $LiCl$is more covalent in comparison to other halides of alkali metals. Due to covalent character, lithium compounds are soluble in organic solvents.
