What is the importance of sodium hydroxide in the preparation of bromoaniline?
Sodium hydroxide is used in the preparation of bromoaniline as a base to deprotonate the aniline compound, making it more reactive towards the brominating reagent. This reaction typically involves a substitution of a hydrogen atom on the aniline molecule with a bromine atom. Sodium hydroxide helps facilitate this reaction by providing the necessary basic conditions for the deprotonation step.
