Vedclass · Answer

(C) Let us analyze each reaction:$(A)$ Benzene to phenol using $V_2O_5$ at $450^{\circ}C$ is not a standard industrial or laboratory method for phenol synthesis. The reaction is incorrect.$(B)$ Dehydration of ethanol $(C_2H_5OH)$ with $Conc. H_2SO_4$ at $140^{\circ}C$ yields diethyl ether $(C_2H_5-O-C_2H_5)$,not dimethyl ether $(CH_3-O-CH_3)$. The reaction is incorrect.$(C)$ Phenol reacts with bromine water $(Br_2/H_2O)$ to form $2,4,6$-tribromophenol as a white precipitate. This reaction is correct.$(D)$ Phenol reacts with dilute $HNO_3$ at low temperature to form a mixture of $o$-nitrophenol and $p$-nitrophenol. The product shown is picric acid ($2,4,6$-trinitrophenol),which is formed by reaction with concentrated $HNO_3$. The reaction is incorrect.Therefore,only $(C)$ is correct.

Which of the following reaction$(s)$ is/are correct?
