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. boohoo brianne high waisted jeans
