Br 2 undergoes electrophilic addition to maleic anhydride as shown in the given reaction. The reason for this reaction being slower than the analogous one with cyclopentene is to be explained. Concept introduction: Molecular bromine undergoes anti addition across a C=C double bond. As the electron-rich alkene approaches Br 2 molecule, it temporarily generates an electron-poor site on the Br atom closer to the alkene. The subsequent flow of electrons takes place between the electron-rich alkene and the electron-poor Br atom. The presence of an electron withdrawing group near to the C=C double bond makes it less electron rich which can diminish the driving force for the electrophilic addition step.
