Find the products obtained by the addition of HBr "to hex -1-ene " (i) in the presence of preoxide (ii) in the absence of peroxide Also write their IUPAC names. (i) Strategy: In the presence of peroxides, the particle that attacks the double bond first is the large bromine atom. It attaches itself to the less hindered carbon atom to form a more stable free radical. The result is anti-Markovnikov's addition. (ii) Strategy: In the absence of peroxides, the particle that attacks the double bond first is a proton ( beacuse a proton is small, steric effect are not important). It attaches itself to a carbon atom by an ionic mechanism to form the most stable carbocation. The result is Markovnikov's addition.
