Question
How is propene converted into 1- bromopropane and 2 - bromopropane?
Advertisements
Solution
The addition of hydrogen halide to an unsymmetrical alkene gives two products.
Propene on reaction with hydrogen bromide forms 80% 2-bromopropane (isopropyl bromide) and 20% 1-bromopropane (n-propyl bromide).
