Testbank, Question 095 What is the expected major organic product from the treatment of 4-methyl-2-pentyne with excess hydrogen in the presence of a platinum catalyst

Answer 1

See explanation and image attached

Step-by-step explanation:

The addition of excess hydrogen to alkyne in the presence of a platinum catalyst leads to complete hydrogenation of the alkyne as shown in the image attached.

Therefore, an alkane is obtained as the major organic product when excess hydrogen reacts with an alkyne in the presence of a platinum catalyst.
