How would you draw the product of the hydrogenation of ethyne?

Answer 1

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.

Answer 2

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.
