Question

What is the action of bromine in alkaline medium on $C{H}_{3}C{H}_{2}N{O}_2$

Answer 1

Primary and secondary nitroalkanes are readily halogenated in alkaline medium. The $\alpha$-hydrogens are replaced by chlorine or bromine. Primary nitroalkanes such as nitro ethane can form mono- and dihalo derivatives, whereas secondary nitroalkanes such as nitro propane can only form monohalo derivative.
