The scent of the tube M components changed drastically after the reaction. The reactants smelled toxic, like plastic or rubber, while the resulting methyl salicylate smelled pleasantly of sweet mint. The contents of tube I also underwent a dramatic shift, in not just scent but also in intensity. While the product smelled strongly of banana, the reactants were weaker; the acetic acid smelled of vinegar and the isopentyl alcohol of chlorine. Tube E experienced the least dramatic shift. The reactants--acetic acid and ethyl alcohol--smelled of vinegar and nail polish remover, respectfully. The product of ethyl acetate smelled like nail polish remover. This tube is the only one to retain the scent of one of its reactants.
