Question

Among toluene and chloroform which is least soluble in water, With reason?

Answer 1

toluene is one hydrogen of benzene is replaced by CH3.
means it has 7 carbon atoms.

but, chloroform CHCl3.
means it has only 1 carbon atom.

as no.of carbons increases non-polar nature increases,as water is a polar solvent it dissolves only polar substances .

So, chloroform is more soluble than toluene.
