Which of the following reaction(s) can be used for the preparation of alkyl halides ? \((I)\,\,CH_3CH_2OH + HCl \xrightarrow{{Anh.\,\,ZnC{l_2}}}\) \((II)\,\,CH_3CH_2OH + HCl \rightarrow\) \((III)\,\,(CH_3)_3COH + HCl \rightarrow\) \((IV)\,\,(CH_3)_2CHOH + HCl \xrightarrow{{Anh.\,\,ZnC{l_2}}}\)
- A \((I)\) and \((II)\) only
- B \((IV)\) only
- C \((III)\) and \((IV)\) only
- D \((I), (III)\) and \((IV)\) only
Answer & Solution
Correct Answer
(D) \((I), (III)\) and \((IV)\) only
Step-by-step Solution
Detailed explanation
\((I)\) and \((IV)\) can be used due to presence of anhydrous \(\mathrm{ZnCl}_{2} (III)\) gives alkyl halide due to formation of more stable carbocation.
