Give 2 anomalous behaviour of Li.

Text Solution

Verified by Experts

The two anomalous behaviour of lithium is-(i) LiOH is a very weak base, while the hydroxides of other alkali metals are strong bases. (ii) The halides of lithium are soluble in organic solvent and many of its compounds are insoluble in water like `Li_2CO_3`, LiF, `Li_3PO_4` etc, while all other alkali metal salts are soluble in water.
