Vedclass · Answer

(B) Steam distillation is a technique used to separate substances which are steam volatile and immiscible in water.It is commonly used for the purification of organic compounds that are sensitive to high temperatures.$p-$nitrophenol is steam volatile due to intramolecular hydrogen bonding,but it is often separated from $o-$nitrophenol using this method.However,the question asks which cannot be purified; actually,all listed compounds are typically purified by steam distillation except those that are highly water-soluble or non-volatile.Given the standard options,$p-$nitrophenol is often cited in textbooks as being steam volatile,but if the question implies a compound that is $NOT$ steam volatile or is highly water-soluble,none of these fit perfectly.However,based on standard competitive exam patterns,$p-$nitrophenol is the intended answer because it is less steam volatile than $o-$nitrophenol due to intermolecular hydrogen bonding.
