1.	Predict the major product(s) of the following reactions, and explain their formation. H_(3)C-CH=CH_(2)underset(HBr)overset((Ph-CO-O)_(2))rarr H_(3)C-CH=CH_(2)overset(HBr)rarr
Answer» Solution :Addition of HBr to PROPENE GIVES 2-Bromopropane. <BR> (i) In presence of organic PEROXIDE the major product is 1-Bromopropane. `underset("Benzoyl peroxide")(C_(6)H_(5))-overset(O)overset(\|\|)(C)-O-O-overset(O)overset(\|\|)(C)-C_(6)H_(5) overset("Homolysis")rarr 2C_(6)H_(5)-overset(O)overset(\|\|)(C)--2C_(6)H_(5)+2CO_(2)` (iii) `C_(6)H_(5)+H-Broverset("Homolysis")rarr C_(6)H_(5)+Br` (iii) (iv) `underset(("Major product"))(CH_(3)-CH-CH_(2)Br)+ Hr+H-Br overset("Homolysis")rarr CH_(3)-CH_(2)-CH_(2)+Br+Br`
