How would you distinguish between methyl benzoate and phenylacetic acid using 1H NMR spectroscopy?
Give the structure of a compound that has a formula of C6H12O and has a triplet (3H 1.1ppm), doublet (6H, 1.2 ppm), quartet (2H 2.4 ppm) and septet (1 H,2.7ppm ) in the 1H NMR spectrum? Please explain how you figured it out.
say you removed an ice cube at -10 ordmc weighing 36 g from your freezer. now you place the ice cube in a 90 g sample
During the distillation of a mixture of two miscible liquids with very different boiling points, the temperature rises to a constant reading and then drops off before returning to a higher reading. Explain the likely cause of this fluctuation in t..
Commercial concentrated nitric acid is 69.0 % by mass HNO3 and has a density of 1.42 g/mL. Calculate the molarity of concentrated nitric acid.
The decomposition of carbon disulfide, CS2 to form carbon monosulfide, CS and sulfur is first order with k = 2.8 x 10^-7 / second at 1000 degrees C. CS2 => CS + S determine how many days would be needed before a 1.00 gram sample of CS2 had decompo..
