Question

What would be the major product of the following reaction sequence? III I IV Equal amounts of II and IV II NBS (N-Bromosuccinimide) is useful in the free radical promoted allylic bromination as shown below. Why is NBS a more practical reagent for this reaction than Br2? Because NBS generates Br2 slowly and keeps the [Br2] low to avoid electrophilic addition to the alkene Because NBS is cheaper than Br2 on a mole basis Because NBS has a high boiling point Because NBS is an organic molecule and is highly soluble in solvents such as CCl4 None of above

Explanation / Answer

15) A ( for detail see mechanism of these reagents) 16) B ( like dissolves like based on highest polarity property) 16) B (NaBr is more stable tha NaI so faster formation of this than NaI so not c!) .. hope it suffice your need!.. still you can message me for any doubt!
