Question

write short note on hydrogenation of alkynes​

Answer 1

Answer:

Hydrogenation of an Alkyne to a Trans-Alkene

Alkynes can be reduced to trans-alkenes with the use of sodium dissolved in an ammonia solvent. An Na radical donates an electron to one of the P bonds in a carbon-carbon triple bond. This forms an anion, which can be protonated by a hydrogen in an ammonia solvent.
