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.
