How would you draw the product of the hydrogenation of ethyne?
There is no specific reaction mentioned, so I'll list all the ones that are relevant.
The highlighted hydrogens are the ones added onto the alkyne.
-
The first one you learned, hydrogen with palladium over carbon, goes all the way to alkane.
-
You can tell that hydrogen with Lindlar's Catalyst stops the hydrogenation at the cis-alkene.
-
The sodium/ammonia radical reaction stops the hydrogenation at the trans-alkene.

The product of the hydrogenation of ethyne (also known as acetylene) is ethane. The chemical equation for this reaction is:
C2H2 + 2H2 → C2H6
The structural formula of ethane is CH3CH3.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
