Question

Why Li compounds are soluble in organic solvents?

Answer 1

Lithium:

• Lithium belongs to alkaline metals.
• It is a silvery metal and floats on water.
• It is a low-dense and highly reactive element.
• It is used for lithium-ion batteries and cells.

$\mathrm{Li}$ solubility in organic solvents:

• Organic solvents are carbon-based solvents that can dissolve one or more substances.
• Lithium compounds are soluble in organic solvents because of their high covalent nature.
• Their high polarizing power is also the reason.
• Other alkali compounds are ionic in nature. So, they are easily soluble in water.
• Lithium compounds are covalent due to Fajan's rule i.e, it is very hard to lose or gain electrons to form an ionic bond as it is the smallest atom.
• The attraction between the outer electrons and nucleus is greater.
• So, lithium compounds are soluble in organic solvents like DMC (Dimethyl carbonate), alcohol and ether.
