Aromatic inductive outcomes are caused by variances in electronegativity between atoms bonded on the ring and the ring carbons. In certain cases the stereoselectivity of halogenation reactions can be considerably eroded by using very polar solvents or electron-releasing substituents on the alkene which will lead to much more stabilized carbocation https://bromuration83837.suomiblog.com/not-known-factual-statements-about-solution-de-bromoforme-53353456
