Infrared (IR) and Nuclear Magnetic Resonance (NMR) are two spectroscopic techniques you've encountered in organic chemistry I, CHM2210. In organic chemistry laboratory, IR and NMR are common tools used to characterize a given product. Consider what you learned in CHM22110, and select the concepts that you feel confident about: a. The theory behind NMR.
b. Identify functional groups based on IR absorptions.
c. I do not recall/understand much about NMR
d. Understanding (de)sheilding
e. correlate the intensity of a 1H NMR signal to the number of protons
f. Deduce the structure of an unknown given its molecular formula, IR and NMR spectra
g. Assigning 13C NMR signals to a given molecule
h. Assigning 1H NMR signals to a given molecule
i. I do not recall/understand much about IR
j. The theory behind IR
k. Identify splitting patterns

Predict whether the changes in enthalpy, entropy, and free energy will be positive or negative for the boiling of water, and explain your predictions. how does temperature affect the spontaneity of this process?

Which explanation is true about what happens to a ray of light when it strikes a mirror? a. a light ray is transmitted toward a mirror at a certain angle. the light ray is then reflected by the mirror at an equal angle but in the opposite direction of the transmitted ray. b. an incident ray strikes a mirror at an angle with a line perpendicular to the mirror. the light ray is then reflected at an angle equal to the angle of incidence but on the opposite side of the perpendicular line. c. a reflecting ray strikes a mirror at an angle with a line perpendicular to the mirror. the light ray is then refracted at an angle equal to the angle of the reflecting ray and on the same side of the perpendicular line. d. an incident ray strikes a mirror at an angle with a line parallel to the mirror. the light ray is then transmitted at an angle equal to the angle of incidence but on the opposite side of the parallel line. you so much! : -d take the time to try and answer correctly.
