regioselectivity
Sign in to saveIn organic chemistry, regioselectivity is the preference of chemical bonding or breaking in one direction over all other possible directions. It can often apply to which of many possible positions a reagent will affect, such as which proton a strong base will abstract from an organic molecule, or where on a substituted benzene ring a further substituent will be added.

A specific example is a halohydrin formation reaction with 2-propenylbenzene: 445px|Regioselectivity in halohydrin formation
