1. 3-methyl-1-butene on reaction with H-Cl forms two products, namely 2-chloro-3- methylbutane (minor) and 2-chloro-2-methylbutane (major). Illustrate the mechanism for the formation of these two products. Use curved arrows to illustrate electron movement and all intermediates must be shown. 2. 3,3-dimethyl-1-butene on reaction with HBr forms two products, namely 3-bromo-2,2- dimethylbutane (minor) and 2-bromo-2,3-dimethylbutane (major). Illustrate the mechanism for the formation of these two products. Use curved arrows to illustrate electron movement and all intermediates must be shown. 3. Calculate...
A reaction of 2-methyl-2-butene with NBS and heat forms both 1-bromo-2-methyl-2-butene and 3-bromo-2-methyl-1-butene. The reason for the formation of multiple products is: a)Markovnikov and Anti-markovnikov addition b)rearrangement of the radical by hydride shift c)resonance structures of the radical d) dibromination products
