Write two properties of lithium carbonate in which it differs from other alkali metal carbonates.
Why is LiF almost insoluble in water whereas LiCl in soluble not only in water but also in acetone?
LiF is almost insoluble in water because of much higher lattice energy than that of LiCl. Since Li+ ion (small size) can polarise bigger Cl- ion more easily than the smaller F- ion, therefore, according to Fajan rules, LiCl has more covalent character than LiF and hence LiCl is soluble in the organic solvents like acetone.
How would you explain that the following observations?
LiI is more soluble than KI in ethanol?
Explain: Lithium exhibits anamalous behaviour in the company of alkali metals.
Or
Name the chief factor responsible for the anomalous behaviour of lithium.
Or
List three properties of lithium in which it differs from the rest of the alkali metals.
In what ways lithium shows similarities to magnesium in its chemical behaviour?
Or
List four properties to show the diagonal relationship between lithium and magnesium.
