Question

Draw the major organic product formed in the following reaction. (the reaction stoichiometry is 1 mol. reactant: 1 mol Br2)

Answer 1

Concepts and reason

The concept used to solve this problem is halogenation at the alpha carbon atom. Here, the reaction occurs in acidic conditions. The halogenation occurs readily with ${\rm{C}}{{\rm{l}}_2},\;{\rm{B}}{{\rm{r}}_2}\;{\rm{and}}\;{{\rm{I}}_2}$ .

Fundamentals

Aldehydes or ketones are reacted with bromine molecule in the presence of an acid forms alpha halo aldehyde or ketone.

The enol form of the substrate is as follows:

The reaction is as follows:
