Question

The yield of the synthesis of diphenylacetylene from stilbene dibromide may be affected by the fact that potassium hydroxide can absorb so much moisture from the air that it looks like a puddle of water. This means that a bottle is never 100 % potassium hydroxide especially after it is opened by multiple students, and not closed quickly and properly. Then the pellets or flakes of potassium hydroxide become sticky and are never completely transferred to the reaction.
