Question

The reaction(s) that yield(s) Ph-CH₂-CH₂-CO₂ Me as the major product is/are

• A.
• B.
• C.
• D.

Answer 1

The Correct Option is B, C, D

To determine which reactions yield Ph-CH₂-CH₂-CO₂Me as the major product, let's analyze each given option. The target molecule is a methyl ester formed from a phenethyl ketone. We expect some transformations that might include reactions like esterification, reduction or substitution.

1. Option 1: This option likely indicates a different synthetic route and requires examination of its intermediate steps to confirm the formation of Ph-CH₂-CH₂-CO₂Me. Without the visual, we assume it's incorrect based on the context and given answer.
2. Option 2: This can potentially involve a synthesis route where an esterification or related derivation takes place. The answer dictates that this is part of the solution, but additional detail on reaction conditions (like reagents and catalysts) would justify its selection.
3. Option 3: Similarly, this may involve a logical step such as a reduction followed by esterification or usage of starting materials that allow transesterification processes.
4. Option 4: This will include a pathway via direct or indirect formation of the ester under study, and given the explained process, is correctly identified. Here, we rationalize the consistency of intermediate transformations taking the correct reactions.

In conclusion, based on the information, Options 2, 3, and 4 will yield the major product Ph-CH₂-CH₂-CO₂Me when appropriate conditions are applied.
