D H OH Br Br Li Li + D O Li Li D O D H hydrocarbons hydrocarbons are compounds containing only the th elements C and H. alkanes C C alkenes alkenes C C aromatics O Br D A B C D E 3 C—C and C—H bonds are notoriously unreactive. Why are they of interest to chemistry and biology? 1. Alkanes are the scaffolds upon which groups are attached to give functional molecules. HO HO O H H O cortisone, cortison e, a steroidal anti-inflammatory drug H HO HO O Choose the correct formula for the following structure: Nomenclature? H alkanes CnH2n+2 = C10H2(10)+2= C10H22 n = 10 C C 2. Hydrocarbons are very hydrophobic, they hate water. This property plays a very important role in the assembly of molecules to form functional structures. Any unambiguous name is acceptable. trimethylheptane A. C10H20 B.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
