Explanation:
A is true: Phosphorus chlorides (tri and penta) are preferred over thionyl chloride for the preparation of alkyl chlorides from alcohols because they are less expensive and more easily available as compared to thionyl chloride. Also, the reaction with phosphorus chlorides is less vigorous and can be easily controlled.
R is true: Phosphorus chlorides give pure alkyl halides because they react selectively with alcohols to give alkyl chlorides without any side reactions. On the other hand, thionyl chloride can also react with other functional groups present in alcohols, such as double bonds and phenolic hydroxyl groups, leading to the formation of unwanted by-products.
R is the correct explanation of A: The reason given in R explains why phosphorus chlorides are preferred over thionyl chloride for the preparation of alkyl chlorides from alcohols. Therefore, option B is the correct choice.
