Bromination, Chlorination, and Halohydrin Formation from Alkenes. Alkenes undergo halogenation when treated with Cl 2, Br 2 and (less commonly) I 2 to give vicinal dihalides; These reactions are stereoselective and give anti-addition products; The mechanism proceeds through a cyclic halonium ion which undergoes backside attack at carbon by a nucleophile to give the anti-addition product.Hybridization in Methylamine (CH3NH2) Hybridization is a theoretical idea that says the atomic orbitals mix and overlaps in a certain way to form new hybrid orbitals which affect the overall molecular geometry and the chemical bonding properties of the participating atoms changing the complete molecule.
