Answer:
See explanation below
Explanation:
First to all, you need to know what is the function of NBS.
N-Bromosuccinimide (NBS) is a brominating and oxidizing agent that is used as source for bromine in radical reactions (for example: allylic brominations) and various electrophilic additions.
In this case, when it's present the light or heat, this agent acts as electrophylic addition, so, instead of going to the double bond, it's going to do an allylic bromination, so the possible products are the following: (See picture)
On January 28, 1986, the NASA shuttle orbiter mission STS-51-L and the tenth flight of Space Shuttle Challenger (OV-99) broke apart 73 seconds into its flight, killing all seven crew members, which consisted of five NASA astronauts and two payload specialists.
