ISATUTORS.COM/UCF 70) View a butane molecule along the C 2 -C 3 bond and provide a Newman projection of the lowest energy conformer. 71) From the perspective of viewing down the C2-C3 bond, draw the Newman projection of the least stable conformation of 2,3-dimethylbutane. 72) In a Newman projection, siting down the C3-C4 bond, draw the structure below in its most stable conformation. 73) Give the IUPAC name for the cycloalkane shown below. 74) Given the following heats of combustion per CH 2 group within the structure, which cyclic alkane has essentially no angle strain? (Ref: long-chain Alkane = 659 kJ/mol)

    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.
