The molecule of p-methylpropiophenone contains a polar carbonyl (C=O) bond and a non-polar benzene ring. The whole molecule is relatively polar, but also has a certain non-polarity. Therefore, it can be dissolved in non-polar solvents such as petroleum ether and benzene, and in polar solvents such as ethanol and dimethylformamide. The molecule of p-methylpropiophenone contains a long alkyl chain and a benzene ring, and there are certain van der Waals forces and hydrogen bonding forces between molecules. These forces make the melting point and boiling point of p-methylpropiophenone relatively high.
