The major product(s) formed in the following reaction sequence is (are)

Options

A2 CH ₃ COOH
BCH ₃ COCOCH ₃
C2 CH ₃ CHO

Correct answer

C. 2 CH ₃ CHO

Step-by-step solution

When 2, 3-dibromobutane react with Zn / Cu in the presence of heat, it forms trans-but-2-ene. Further O ₃ and Zn / H ₂ O is used for reductive ozonolysis of trans-but-2-ene and forms 2 moles of CH ₃ CHO i.e., acetaldehyde.
