Kevlar is the DuPont Company's brand name for material made out of synthetic fiber of poly-paraphenylene terephthalamide which is constructed of para-aramid fibers that the company claims is five times stronger than the same weight of steel, while being lightweight, flexible and comfortable. It is also very heat resistant and decomposes above 400 °C without melting. It was invented by Stephanie Kwolek of DuPont from research into high performance polymers, and patented by her in 1966 and first marketed in 1971. Kevlar is a registered trademark of E.I. du Pont de Nemours and Company. Originally intended to replace the steel belts in tires, it is probably the most well known name in soft armor as bulletproof vests. It is also used in extreme sports equipment, high-tension drumhead applications, animal handling protection, composite aircraft construction, fire suits, yacht sails, as an asbestos replacement, and recently, even in R/C model helicopter blades and sometimes in loudspeaker cones.

1-C Hydroboration puts -OH on least substituted C; anti-Markownikov\n2-B Correct\n3-A Correct\n4-C Br goes on the center C; product has two identical CH3CH2- groups on center C, therefore symmetrical and achiral\n5-A Correct\n6-A Correct\n7-B Correct\n8-A Correct\n9-C Markownikov addition puts H on C next to C-CH3 and OH onto HO-C-CH3

This compound is an amine.  You can identify it by the NH2 (amine group) at the end.  You did a fair job with the structure considering the limits of the text here.  I am sure you realize that two of your carbons do not have the correct number of bonds.

I agree with birchardv here...........we need the rest of the problem, and you would learn a lot more if you did the homework yourself.  But do whatever floats your boat.  Add the rest of the problem and I'll get back to you.\n\nOkay Chemist, this problem is really long; if you want a good answer with plenty of steps, I'll need more room.  Email me and I'll send you the solution.
