WebThe presence of electron-withdrawing groups (such as nitro) ortho and para to the chlorine substantially enhance the rate of substitution, as shown in the set of equations presented on the left below. To explain this, a third … WebDec 8, 2024 · Why is chlorine meta directing? Cl is meta directing. Hint: Chlorine has a lone pair so it can donate electrons to the benzene ring. Chlorine has high electronegativity so it can withdraw the electron density from the ring. So, they direct the attacking group at different positions of the benzene ring. WebJan 28, 2016 · This is why an alkoxy group is more activating than a halogen. Oxygen does have a higher electronegativity than does chlorine, bromine or iodine. However, oxygen's orbital overlap with carbon allows it to more readily donate into the ring's pi system. The larger halogens aren't able to do this (to an appreciable extent). kettle instruction manual
