Question

Write the reaction of 2-butyne with Lindlar catalyst.

Answer 1

Answer:

CH3-C=C-CH3

Explanation:

Answer 2

The reaction of 2-butyne with Lindlar catalyst produces cis-2-butene as the final product

- Lindlars catalyst is known as H2 + Pd/BaSO4

-the actual reaction of lindlars catalyst on 2-butyne is given as under:

CH3-CC-CH3 (2-butyne) + H2 & Pd/BaSO4 (lindlars catalyst) ----> CH3CH=CHCH3 (cis-2-butene)

-it can be clearly seen that the lindlars catalyst acts on 2-butyne and converts it into cis-2-butene
