Statement I: Phosphorous chlorides (tri and penta) are preferred over thionyl chloride for the preparation of alkyl chlorides from alcohols
Statement II: Phosphorous chlorides give pure alkyl halides
Answer & explanation
Correct answer: option 4
The answer is option 4. Both statement I and Statement II are incorrect.
Correct Statement I: Thionyl chloride is preferred over \(PCl_3\) and \(PCl_5\) for the preparation of alkyl chłorides from alcohols.
Correct Statement II: Thionyl chloride gives pure alkyl halide as other two products \((SO_2 + HCl)\)are escapable gases.
