$2-$Hexanol and $2-$hexanone

Vedclass · Answer

(C) Tollens' reagent is an oxidizing agent used to distinguish between aldehydes and ketones. Aldehydes (like benzaldehyde,hexanal,and pentanal) react with Tollens' reagent to form a silver mirror,whereas ketones (like $2-$hexanone) and alcohols (like benzyl alcohol and $2-$hexanol) do not react. In the pair $2-$hexanol and $2-$hexanone,both compounds fail to react with Tollens' reagent because $2-$hexanol is a secondary alcohol and $2-$hexanone is a ketone. Therefore,they cannot be differentiated using this reagent.

Which of the following pairs cannot be differentiated by Tollens' reagent?
