WebDescription: When ethers are treated with strong acid in the presence of a nucleophile, they can be cleaved to give alcohols and alkylhalides. If the etheris on a primary carbon this may occur through an SN2 pathway. Notes: Common acids for this purpose are HI and other hydrogen halides, as well as H2SO4in the presence of H2O. WebPhenyl halides The lack of a uniform order of relative reactivity of the halogens in reactions of certain nucleophiles with nitro- and polynitro-phenyl halides led Parker and Read to propose a one- stage mechanism for some aromatic nucleophilic substitutions.

Unlike typical alkyl halides, aryl halides typically do not participate in conventional substitution reactions. Aryl halides with electron-withdrawing groups in the ortho and para positions, can undergo SNAr reactions. For example, 2,4-dinitrochlorobenzene reacts in basic solution to give a phenol: Unlike in most other substitution reactions, fluoride is the best leaving group, a… WebApproach 1: Conversion of Alcohols to Alkyl Halides with HX Both, the substrate and the acid affect the conversion in the following way: 1) The strength/reactivity of the acid, hence the efficiency of the conversion is increasing in the following order: HCl < HBr < HI 2) More substituted alcohols usually react more rapidly with HX:
