Hydrogenation of Alkynes

The video tutorial by Professor Dave explains the process of hydrogenation in organic chemistry, focusing on the conversion of alkynes to alkanes and alkenes. It covers the use of palladium for full hydrogenation, Lindlar's catalyst for producing Z alkenes, and methods involving lithium or sodium for E alkenes. The tutorial emphasizes the stereochemistry involved in these reactions and provides practical examples to illustrate the concepts.

What are the conditions under which an alkyne can be converted to a Z alkene?

How does the use of lithium and ammonia affect the hydrogenation of alkynes?

Summarize the three different methods of hydrogenation discussed in the text.
