Which of the following reaction(s) can be used for the preparation of alkyl halides?

i)

C{H_3}C{H_2}OH + HCl\xrightarrow{{\mathrm{Anhyd}\mathrm{.ZnC}{\mathrm{l}_2}}}

ii)

C{H_3}C{H_2}OH + HCl \to

iii)

{(C{H_3})_3}COH + HCl \to

iv)

{(C{H_3})_2}CHOH + HCl\xrightarrow{{\mathrm{Anhyd}\mathrm{.ZnC}{\mathrm{l}_2}}}

View answer and explanation

Correct option: C

I, III and IV only

Option C (I, III and IV only) is correct because primary, secondary, and tertiary alcohols can react with HCl to form alkyl halides, sometimes requiring a catalyst like anhydrous

ZnCl_2
