(ii) (CH_3)_3CBr+KOH \xrightarrow [heat]{ ethanol }
(iii) CH_3CH(Br)CH_2CH_3 + NaOH \xrightarrow []{water}
(iv) (CH_3)_3CBr+KOH \xrightarrow [heat]{ ethanol }
(v) C_6H_5ONa + C_2H_5Cl \longrightarrow
(vi) CH_3CH_2CH_2OH + SOCl_2 \longrightarrow
(vii) CH_3CH_2CH = CH_2 + HBr \xrightarrow [ ]{peroxide}
(viii) CH_3CH = C(CH_3)_2 + HBr \longrightarrow
