Question

The major product formed in the following reaction sequence is 

• A. (A)
• B. (B)
• C. (C)
• D. (D)

Hint:

In reductions using TiCl₃ and Cu-Zn, aldehydes are typically reduced to primary alcohols. Be sure to follow the reaction sequence step by step.

Answer 1

The Correct Option is C

Step 1: Understanding the reaction steps.
- In the first step, the TiCl₃ and Cu-Zn reagents are typically used for reducing a carbonyl group in an aldehyde (like the given structure) to an alcohol. This is a reduction reaction, converting the aldehyde group into a primary alcohol.
- The second step, using HCl and water, is an acidic hydrolysis step. This step does not affect the alcohol group, but might affect other functional groups present. In this case, it does not alter the product significantly.

Step 2: Analyzing the options.
- Option (A) is incorrect as it represents a different functional group than expected.
- Option (B) is incorrect as it does not fit the expected transformation from aldehyde to alcohol.
- Option (C) is correct as it shows the aldehyde being reduced to a primary alcohol, consistent with the reaction steps.
- Option (D) is incorrect as it involves a different transformation.

Step 3: Conclusion.
The major product formed is the primary alcohol shown in option (C).
