HBr Addition to an Alkene. HBr adds to alkenes to create alkyl halides. A good way to think of the reaction is that the pi bond of the alkene acts as a weak nucleophile and reacts with the electrophilic proton of HBr. Alternatively, you can view the first step of the reaction as the protonation of the pi bond.

The structures of the products are shown in figure 1. ... Whereas, 2-Methyl-2-butene is the major product. This is because major product is the more substituted product which makes it more stable compared to the minor product. That is why we produced more of 2-Methyl-2-butene compared to 2-Methyl-1-butene.

Colloids are classified into two types in the cases where dispersion medium is water. They are:(i) Hydrophilic or Lyophilic colloids : Those substances, which when mixed with the dispersion medium, form directly the colloidal solution and are termed as hydrophilic colloids. They are reversible solutions, quite stable and cannot be easily precipitated.Example : gum, gelatine, starch, rubber etc.(ii) Hydrophobic or Lyophobic colloids : Those substances which do not form colloidal solution when simply mixed with the dispersion medium, are called hydrophobic colloids. They are irreversible solutions, unstable and can be easily precipitated. Example : Metals and their sulphides
