Concept explainers
Interpretation:
It is to be explained at which magnetic field experienced by a hydrogen nucleus is the energy difference between the
Concept introduction:
Protons have quantized magnetic dipoles and thus behave as tiny bar magnets, with a north and a south pole. When exposed to
The difference in energy between the two spin states of a proton is given by the equation:
The energy difference,
Answer to Problem 16.1P
The energy difference will be greater at
Explanation of Solution
The difference in energy between the two spin states of a proton is given by the equation:
The energy difference,
Thus, at greater external magnetic field,
The magnetic field experienced by hydrogen nucleus, at which the energy difference between the

- Draw a diagram analogous to Figure 11.15, but now representing an electrons spin and its z-component. How many cones are there?arrow_forwardLabel below statement as True or False. When a nucleus is strongly shielded, the effective field is smaller than the applied field and the absorption is shifted upfield .arrow_forwardAa.53.arrow_forward
- An ē at its excited state is stable unti it return to its ground state. If an ē jumped more than one energy levels because of absorption of a high E, the process of the ē returning to its ground state is direct and straightforward transitio to lowest energy level. Which of the statements is true? Both are not true Both statements are true only the first statement is true only the second statement is truearrow_forwardCompute for the linear equation of the following concentration and absorbance given in the table.

- Two signals appear in the 1H NMR spectrum of thecompound shown here. One has twice the integration ofthe other. The signal with greater area corresponds to achemical shift of 9.3 ppm. The signal with less areacorresponds to a chemical shift of -2.9 ppm. Explain.Hint: Consider the magnetic field lines from a ring currentarrow_forwardPlease provide the solution to the attached problemarrow_forwarda The structure of 2 chloroethanol is usually staggered, as shown in this Newman projection: How many distinct 1HNMR signals would you expect from this molecule? Assume that the OH bond is pointing away from the CC bond. b In some circumstances, 2 chloroethanol can be frozen in an eclipsed structure, whose Newman projection looks like this: How many distinct 1HNMR signals would you expect from this molecule?arrow_forward
- Please analyze this spectraarrow_forwardTrue or False: The chemical shift of a particular proton provides information about the electronic/chemical environment of that proton. Could you explain how to do this in detail?arrow_forwardExplain how to differentiate A) Alkane from Primary Amine B) Alkane from Ether C) Primary Amine from Ether on an Infrared spectrum.
