CHM 132 Midterm: General Inorganic Chemistry 2 Midterm 1

Consider the spectroscopic techniques (short answers please)

1) what kind of photons do NMR instruments detect?

2) what do these photons tell you about the molecule being scanned?

3) what kind of photons do IR spectrometers detect?

4) what do these photons tell you about the molecule being scanned?

5) what advantages and disadvantages do each technique have?

In cyclic voltammetry, working electrode potential is scanned from negative to positive direction. Why the current does not increase linearly with the increase of potential (Ohm's law)? In fact, a peak of current is observed

Assign as specifically as possible all of the carbon and proton environment in the spectra to the protons and carbons in the structure of the product. You should be able to assign peaks that correspond to carbons and protons that stand out well from each other
