Quizplus · Accepted Answer

The reaction sequence involves oxidation of the primary alcohol to form an aldehyde using PCC (pyridinium chlorochromate), followed by a Wittig reaction with Ph3PCH2 and then the product is subjected to reduction using LiAlH4 to form a primary alcohol. In the Wittig reaction, the Ph3PCH2 acts as a nucleophile attacking the carbonyl carbon of the aldehyde, leading to the formation of an alkene. The aldehyde used in this reaction is propanal, which upon reaction with Ph3PCH2, forms (Z)-2-phenylprop-2-en-1-ol. This product upon reduction using LiAlH4 will yield 2-phenylpropan-1-ol as the major product. The structure of the major product is given in choice C.
