REVIEW Topics [References) CH HC OCH Br2 CH3 B H3C CH,OH H₂C CH₂ Electrophilic addition of hypohalous acids to alkenes yields a 1,2-haloalcohol called a halohydrin. Halohydrin formation, however, does not result from the addition of HOBr, for example. Instead the addition is done indirectly by reaction of the alkene with Br, in the presence of water. The reaction also works with Cl2 to give chlorohydrins instead of bromohydrins. The reaction proceeds through a cyclic intermediate known as...

I have a question over Problem 9.36 from David Klein’s Chapter 9
on Addition Reactions of Alkenes.
I’ve noted acid-catalyzed hydrations in Chapter 9 don’t seem to
note anything about their properties of syn- or anti- addition
processes.
Why don’t acid-catalyzed hydrations contain descriptions of
whether they’re anti- or syn- additions? I know that the compound
in Problem 9.36 doesn’t contain a hydrogen whose stereochemistry
would matter, but what about the acid-catalyzed hydrations with
hydrogens whose stereochemistry does matter?
