Question

Answer 1,2,3,4 please thank you!

Aniline is very readily brominated in aqueous conditions at room temperature in comparison to benzene (high temperature and FeBr3 catalysis is required). When aniline is treated with 3 moles of bromine in water at room temperature, the following product is obtained. Why? NH2 NH2 Br Br2 (3moles) H2O 100% Br 4. Why are esters more deactivating that ketones?
