Chemistry Question on Alcohols, Phenols and Ethers

A fruity smell is obtained by the reaction of ethanol with

A

CH3COCH3CH_3COCH_3

B

PCl5PCl_5

C

CH3COOHCH_3COOH

D

CH3CHOCH_3CHO

Answer

CH3COOHCH_3COOH

Explanation

Solution

 Alcohol ROH+ acid RCOOH ester(RCOOR)\underset{R OH }{\text { Alcohol }}+\underset{R COOH }{\text { acid }}{\rightleftharpoons} \underset{(R COOR )}{\text { ester}} (fruity smelling)
alcohol (C2H5OH)\left( C _{2} H _{5} OH \right) when react with acid they produce ester and esters have fruity smell.
C2H5OHEthyl alcohol+CH3COOHAcetic acidC2H5COOCH3 Fruity smell of ester\underset{\text{Ethyl alcohol}}{C _{2} H _{5} OH} + \underset{ \text{Acetic acid}}{CH _{3} COOH} \longrightarrow \underset{\text{ Fruity smell of ester}}{C _{2} H _{5} COOCH _{3}}
