Also explain which are the kinetic and thermodynamic products.Which of the following statements describes accurately the mechanism of the bromination of alkenes? Choose all that apply. O As a consequence of the cylic bromonium ion and anti-addition, a maximum two stereoisomers are formed even though the dihalide product may have two chiral carbons. O Instead of a carbocation intermediate, bromination forms a cyclic bromonium intermediate. O A symmetric cis alkene will form only stereoisomer that is a meso compound O The mechanism of the bromination of alkenes is absolutely the same as the general mechanism of electrophilic addition of alkenes. O The bromide ion can only add to the side opposite the C-Br bonds of the bromonium ion because of steric hindrance.
