Concept explainers
(a)
Interpretation:
The most basic site in the given species is to be determined.
Concept introduction:
Basicity of a compound depends on the
pKa value of a functional group in different compounds is similar in the absence of resonance involving the functional group.
This concept can be used to compare the basicity of different functional groups that may be present in a compound.
(b)
Interpretation:
The most basic site in the given species is to be determined.
Concept introduction:
Basicity of a compound depends on the functional groups present in it. The pKa value of a functional group determines its acidic strength as well as the strength of its conjugate base. The conjugate base formed from a weak acid is strong, and the conjugate base formed from a strong acid is a weak. The higher the pKa, weaker the acid and therefore stronger the conjugate base.
pKa value of a functional group in different compounds is similar in the absence of resonance involving the functional group.
This concept can be used to compare the basicity of different functional groups that may be present in a compound.

- How many signals do you expect in the H NMR spectrum for this molecule? Br Br Write the answer below. Also, in each of the drawing areas below is a copy of the molecule, with Hs shown. In each copy, one of the H atoms is colored red. Highlight in red all other H atoms that would contribute to the same signal as the H already highlighted red. Note for advanced students: In this question, any multiplet is counted as one signal. Number of signals in the 'H NMR spectrum. For the molecule in the top drawing area, highlight in red any other H atoms that will contribute to the same signal as the H atom already highlighted red. If no other H atoms will contribute, check the box at right. No additional Hs to color in top molecule For the molecule in the bottom drawing area, highlight in red any other H atoms that will contribute to the same signal as the H atom already highlighted red.

Some important Notes: • Draw the major product, or products, of the reaction in the drawing area below. • If there aren't any products, because no reaction will take place, check the box below the drawing area instead. • Be sure to draw bonds carefully to show important geometric relationships between substituents. Note: if your answer contains a complicated ring structure, you must use one of the molecular fragment stamps (available in the menu at right) to enter the ring structure.
