Question

Write an equation for the reaction of bromine at room temperature with

a. propene

b. 4-methylcyclohexane

Answer 1

(a) when bromine is treated with propene. (CH3 CH=CH₂) then bromine at one are are added to each carbon atoms slong carbon- carbon double bond. The bromine (Bre) lases it's zriginal colour (red brown colone) to give a colorless liquid. Here the product, 1,2-dibrouro propone is formed.

(6) The name of the react ant will be 4-methyl cyclohexene mot 6-methyl- cyclohexane Similarly here also bromine atoms.
