Question

What product is obtained when acetylene undergoes hydrogenation in presence of Lindlar Catalyst? Answer
A. O Ethene
B. O Ethane
C. O Methane
D. O 1,3-Butadine ​

Answer 1

Answer:

The hydrogenation of alkynes with such catalysts can result in the formation of alkanes (the alkene products undergo further hydrogenation under the influence of the catalyst). In order to obtain only alkenes as the product, the catalyst must be poisoned with substances that reduce its activity.
