Phenol can be prepared from  C6H5Br

 

a. reaction with NaOH at room temperature

b. Treatment with Mg,followed by reaction with oxygen and hydrolysis

c. Treatment with Mg,followed by hydrolysis

d.All of these..

 

plz give ur eq with d ans.....

i think so the most appropriate answer is (b)...............

 

because..........                                O_{2                                       H+}

C6H5Br  + Mg -- >   C6H5MgBr ----->  C6H5OMgBr----> C6H5OH

 

HOPE U UNDERSTAND IT................

i m not saying that others cant make phenol ..............but i m not sure abt them............but the best method is this only...............

 

thanku............
