+ 1 more questions by taankkkkk
hey guys now when bromine is added to ethene and ethyne, it is given in dalal that brown colour of bromine is discharged which serves as a test for unsaturation
1) bromine is getting added to the unsaturated compound, then how can it be released
2) the reddish brown liquid bromine obtained when passed through alkyne makes it colourless, is this also the case for alkenes?
because in 2015 paper this is the question asked
