WebJan 23, 2024 · The order of reactivity among Halogens from the more reactive (least deactivating substituent) to the least reactive (most deactivating substituent) halogen is: F> Cl > Br > I The order of reactivity of the benzene rings toward the electrophilic substitution when it is substituted with a halogen groups, follows the order of electronegativity. Web2KBr + Cl₂ → 2KCl + Br₂ , chlorine has displaced bromine as it is more reactive Explain why fluorine is more reactive than chlorine Fewer shells/electrons, less shielding (or stronger attraction from nucleus), easier to gain electrons Explain why potassium is more reactive than lithium (3 marks)

WebFeb 13, 2016 · Fluorine is clearly more reactive than chlorine. It is arguably more reactive than any other element on the Periodic Table. Electronegativity increases across a Period … WebJun 27, 2013 · HCl and HF are stronger acids than H 2 O because Cl-and F-are much weaker bases than OH-.Those bond energies you wrote refers only to homolitic dissociation: H-Cl --> H. + Cl. and not to ionic dissociation: H-Cl --> H + + Cl-.Ionic dissociation energies are much different; looking for them you should find that OH- is much more reactive than Cl- or F- … WebDec 3, 2014 · It is difficult for them to get close to the anions. The result is that the nucleophile has few molecules in its solvent shell. The nucleophile can more easily attack the substrate. F⁻ becomes a much better nucleophile. In polar aprotic solvents, the order of nucleophilicity is reversed: F⁻ > Cl⁻ > Br⁻ > I⁻ Answer link rntbcs
