(a)    (i)    Phenol to Benzene

                

        (ii)    Propene to Propanol

                CH_3=CH_2 + HCl \xrightarrow {\textup{peroxide}} CH_3CH_2Cl \xrightarrow {aq.\textup{ KOH}} CH_3CH_2CH_2OH

(b)    O-nitrophenol is more acidic than o-methoxyphenol since -NO_2 is an electron withdrawing group, it increases acidic strenth by stablising the phenoxide ion due to dispersal of negative charge whereas -OCH_3 being an electron releasing group decreases the acidic strength of phenol by destabilizing the phenoxide ion due to increase of negative charge.
