Question

Identify product [A], [B], and [C] in the following reaction sequence.


 

• A.
• B.
• C.
• D.

Hint:

For reactions involving alkyne to alkene conversion, ozone and further reduction reactions, always remember the key intermediates and their transformations.

Answer 1

The Correct Option is A

In this reaction sequence: 
- The Pd/C reduction of the alkyne leads to an alkene [A]. 
- Ozone cleavage of the alkene gives an aldehyde [B], and further reduction with Zn and water forms an alcohol [C].
