WebAromatic halogenation with bromine, chlorine, or iodine gives the corresponding aryl halides. This reaction is typically catalyzed by the corresponding iron or aluminum trihalide. The Friedel–Crafts reaction can be performed either as an acylation or as an alkylation. Web11 aug. 2024 · INDUCTIVE EFFECT Vs RESONANCE EFFECT • In most of the cases, resonance effect is stronger and outweighs inductive effect. • For example, the -OH and -NH2 groups withdraw electrons by inductive effect (-I). However they also release electrons by delocalization of lone pairs (+R effect).

WebThe inductive effect is due to the difference in electronegativity of atoms bonded together. A bond between two atoms is polarized if there is a difference between their electronegativities. This polarization of the bond causes the appearance of partial charges + δ and − δ, which have effects on the neighboring bonds at a relatively short distance. Web22 sep. 2010 · Predictably, this effect is going to be related to two major factors: 1) the electronegativity of the element (the more electronegative, the more acidic) and the distance between the electronegative element and the negative charge. 5.
