WebAnd in excess of HI, the alkoxide undergoes subtitution reaction and gives alkyl halide as C 2H 5I. Thus (i)= C 2H 5I. Ethers can be most commonly prepared by Williamson's … WebNotes: The third example could also be written “H 3 O+” . Note that excess HI will convert primary alcohols to alkyl halides via SN2, but not phenol (C 6 H 5 OH) since sp 2 hybridized carbons do not undergo S N 1 or S N 2 reactions.. Mechanism: Strong acid (HI) protonates the ether oxygen, which turns it into a better leaving group (Step 1, arrows A and B). …
