Question

What is the production of hydrogenation of trans-2-butene?

Answer 1

Hint :In hydrogenation, double and triple bonds get broken to single bonds. Thus, the double bond in trans-2-butene gets reduced to a single bond.

Complete Step By Step Answer:
The product of hydrogenation of trans-2-butene is simple butane.
Hydrogenation is a reaction in which triple bonds get reduced to double bonds, and double bonds get reduced to single bonds. It is a chemical reaction in which molecular hydrogen and any other compound are subjected to a chemical reaction under the presence of a catalyst such as nickel, palladium or platinum.
Now, there is a double bond in the given compound i.e. trans-2-butene. As hydrogenation reduces the double bond to single, here also the same will happen.
The below given figure is of trans-2-butene.

Now, after hydrogenation the double bond gets broken into a single bond, and thus both the carbon atoms get an extra hydrogen to comply with the reduced double bond.
The below given is the product after hydrogenation, which is just simple butane.

Thus, if any element or compound is subjected to a chemical reaction with molecular hydrogen, it undergoes hydrogenation and loses its triple bond to double bond and its double bond to single bond. Double hydrogenation on triple bonds can make it a single bond.

Note :
Any compound can reduce its double or triple bond to single through hydrogenation. There are other methods too, but this method is more reliable on most of the compounds.
