Question

Predict the major organic product of the following reaction. When drawing hydrogen atoms on a carbon atom, either include all hydrogen atoms or none on that carbon atom, or your structure may be marked incorrect

Answer 1

Ans: + H- Br Br "Mat ajor Mechanism Product) (Major Product Mechanism (Cambocation) As 3 carbocation is more stable so H will be added in less substitute carbon atom and the nucleophile Bp will add at the more substitute carbon atom of the alkene... This product is called arkovnikoff - product.

Ans: HBY Mechanism omegn H-Kyo + will also follory Markoynikoff This reaction will also follory M path, where nucleophile adds to the more substituted carbon atom of alken bu KD

Ans: + Hel - Xa Mechanism om sy (30 cap bocahon) This reaction will also follow the Markon- Ki Markovnikoff's pathway through more substituted 3 - carbocation. se od Nehoda
All the above reaction of HBr addition to an asymmetrical alkene will follow the Markovnikoff's rule of addition of nucleophilic bromide anion to the more substituted carbon atom.
