Vedclass · Answer

(C) The reaction between a ketone (cyclohexanone) and an alcohol (cyclohexanol) in the presence of an acid catalyst $(H^+)$ leads to the formation of an acetal. Since the alcohol is present in excess,the reaction proceeds to form a ketal (a type of acetal). The ketone carbonyl oxygen is protonated,followed by the nucleophilic attack of the first molecule of cyclohexanol to form a hemiacetal intermediate. $A$ second molecule of cyclohexanol then attacks the intermediate,leading to the loss of water and the formation of the final ketal product,$1,1$-dicyclohexyloxycyclohexane.
