1) How to distinguish alkane, alkene, and benzene by doing Br2 test?
2) Which compound will make the red color disppear?
1.
alkane and Benzene doesnt react with Br2 test
alkene react wiith Br2 form the dibromo compound
alkane doesnt have any functional group so Br2 directly cannot react alkane
alkane only react with Br2 in the prescence of light
whereas alken eis having unsaturation whrn you treat this alken ewith Br2 water
Br2 will add acorss the double bond and gives dibromo compound
though Benzene is having unsaturation it doesnt directly react with Br2 because of its highly stabilised resonence energy
2.
alkene only make disappear the red color of bromine
