Question

Which of the following reaction(s) can be used for the preparation of alkyl halides?
I. $CH _3 CH _2 OH + HCl \xrightarrow{\text { Anhyd. } ZnCl _2}$
II. $CH _3 CH _2 OH + HCl \longrightarrow$
III. $CH _{33} COH + HCl \longrightarrow$
IV. $CH _{32} CHOH + HCl \xrightarrow{\text { Anhyd. } ZnCl _2}$

• A. I III and IV only
• B. I and II only
• C. IV only
• D. III and IV only

Answer 1

Answer: (A)

I and IV can be used due to presence of anhydrous $ZnCl _2$ (III) which gives alkyl halide due to formation of more stable carbocation.
