Question

Which is the regioselectivity of hydrohalogenation reaction and underlying reason of this regioselectivity.

O Markovnikov addition: Alkene will accquire proton using the less substituted C so that it will produce more stable carbocation on the more substituted C. Markovnikov addition: Alkene will accquire proton using the more substituted C so that it will produce more stable carbocation on the more substituted C. anti-Markovnikov addition: Alkene will accquire a halide ion using the less substituted site to avoid larger steric hindrance from the more substituted site. anti-Markovnikov addition: Alkene will accquire a proton using the less substituted site to avoid larger steric hindrance from the more substituted site.

Answer 1

• It will follow the markoni kov addition rule. Alkene will follow acquire Proton using Substituted 'C' so that it will produce more Carbocation on the more substituted 'C. the less stable to understand this lete take an example : - Wat u (alkene attacks) Xh+of tres case 0 - case@ al kene attacks ) on Bouton ha here we take hath Polibilt49. " Case 2 Carbocation is more stable. so later co attacks of Cadbolation, and rooms final product. (case 2) on mae Substituted 'C. this is So a helofen goes Markoni kov Rule.
