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

Reaction sequence:
- Pd/C reduction of alkyne yields alkene [A].
- Alkene ozonolysis forms aldehyde [B]; subsequent Zn/water reduction produces alcohol [C].
