Dear student
Please find the solution to the asked query:

A compound ' X ' with molecular formula C3H6 burns with a sooty flame  and decolourises bromine water.
This means that the compound has a double bond.
The compound is Propene, CH3CH=CH2
Its reaction with Bromine water is shown below, which leads to formation of 1,2, dibromopropane.
