When a terminal alkene undergoes hydroboration-oxidation, two constitutional isomers are possible, but only one isomer is observed as the major product. Such reactions are described as stereospecific constitutionally constrained regioselective stereoselective regiospecific The mechanism of hydroboration-oxidation must explain the observed addition of the \( \mathrm{H} \) and \( \mathrm{OH} \) to the alkene as well as the regiochemistry. anti; Markovnikov stepwise; mixed anti; anti-Markovnikov syn: anti-Markovnikov syn: Markovnikov
