Homework Answers
1st compound is completely non polar. Hence it's solubility is more in non polar solvents. Hence, hexane is the suitable solvent for this.
2nd compound has polar groups attached to it. Hence it prefers polar solvent like 95% ethanol.
3rd compound also has non polar component more. Hence hexane is the suitable solvent.
4th compound is urea. It is highly soluble in water. Hence, water is the suitable solvent.
