Double dehydrohalogenation on an alkane usually requires a very strong base like NaNH2 why is KOH strong enough to do this reaction with stilbene dibromide to obtain diphenylacetylene?

It is possible to make KOH work for the double dehydrohalogenation of an alkane if the base is in a high concentration. If a solvent like triethylene glycol is used, KOH will be less solvated than in solutions of say water, and therefore act as a stronger base.

How is endothermic reaction identified?
It requires heat as a reactant.
What is a endothermic change?
The change occured due to the endothermic reaction i.e. ( the reaction which requires heat to react ) is called endothermic change.
Is the splitting of water into hydrogen and oxygen a exothermic reaction?
No. It is endothermic as it requires energy.
What is the difference of endothermic reaction from exothermic reaction?
An endothermic reaction requires heat to form products. An exothermic reaction produces heat when it forms products.
