4 what is the ftir interpretation of 1-chloro-1-methylcyclohexane?
I have the following data from an NMR scan. Five peaks; a doublet at about 0.8ppm (6H) a small single septet at about 1.5 ppm (1H), a triplet at 1.6 ppm (2H(, a singlet at about 2.1 ppm (3H), a triplet at about 4.4 ppm (2H). The molecular formula is C7H14O2. I calculated a degree of unsaturation of 1. I have tentatively identified the compound as methyl-4-methylbutanoate. I would appreciate any comments you care to make. Thank you.

Identify the most stable, second most stable, and least stable conformation resulting from rotation about the bond indicated by the purple arrow. Assume, in this context, that the methoxy group is sterically smaller than the methyl group, an assumption that is supported by the fact that methoxy groups induce less axial strain than methyl groups in cyclohexane conformations.

Three liquid samples of known masses are heated to their boiling points with the use of a heater rated at 500.0 W. Once the boiling points of each sample are reached, the samples are heated for an additional 4.96 min, which results in the vaporization of some of each sample. After 4.96 min, the samples are cooled and the masses of the remaining liquids are determined. The process is performed at constant pressure. The results are recorded in the table. Liquid CH₂OH Boiling point (°C) 64.5 C4H10 -1.00 C6H6 80.1 Initial mass (g) Final mass (g) 465.2 340.37 496.1 95.69 683.6 339.68 Calculate the molar enthalpy of vaporization, AHvap, and the molar entropy of vaporization, ASvap, for each sample.
