Question

Addition of HCl to 2-methyl-2-butene mainly gives

Answer 1

2-Chloro -2-methyl - butane

Answer 2

Answer:

HCl addition to 2-methyl-2-butene forms 2-chloro-2-methylbutane.

Explanation:

• Addition of HCl to 2-methyl-2-butene [CH₃-(CH3)CH=CH-CH₃] follows electrophilic addition reaction. It occurs as follows:

1. HCl dissociates into H⁺ and Cl⁻ ion. The H⁺ ion(electrophile) attacks double bond forming a positive ion on 2nd carbon and negative charge on 3rd carbon according to Markonikov rule.
2. The H⁺ ion binds to 3rd anionic carbon.
3. The Cl⁻ ion then attacks the cationic 2nd carbon and form 2-chloro-2-methylbutane[CH₃-(CH₃)CHCl-CH₂-CH₃] as final product.
