students are advised to dispose of the 95% ethanol mother liquor from the recrystallization step n the nitration of bromobenzene in a waste bottle for halogented wastes while the same solvent used for the recrystallization step in the nitration of methyl benzoate is disposed of ina non-halogenated waste bottle. Explain this apparent contradiction.
