Interpretation:The conjugate acid base pairs present in the equation
Concept Introduction:An acid and base pair with the gap of one proton(presence or absence) is called a conjugate acid-base pair.
a.

Answer to Problem 8A
HF,F- and H3O+,H2O are the two conjugate acid base pairs in the reaction where HF and H3O+ are the acids and F- and H2O are the bases.
Explanation of Solution
HF,F- have a proton difference of 1 with HF being an acid and F- being the Lewis base.
H3O+,H2O have a proton difference of 1 with H3O+ being an acid and H2O being the Lewis base. So both of them can be considered conjugate acid-base pairs.

Answer to Problem 8A
HCN,CN- and H2O,OH- are the two conjugate acid base pairs in the reaction where HCN and H2O are the acids and CN- and OH- are the bases.
Explanation of Solution
HCN,CN- have a proton difference of 1 with HCN being an acid and CN- being the Lewis base.
H2O,OH- have a proton difference of 1 with H2O being an acid and OH- being the Lewis base. So both of them can be considered conjugate acid-base pairs.

Answer to Problem 8A
H2CO3,HCO3- and H2O,OH- are the two conjugate acid base pairs in the reaction where H2CO3 and H2O are the acids and HCO3- and OH- are the bases.
Explanation of Solution
H2CO3,HCO3- have a proton difference of 1 with H2CO3 being an acid and HCO3- being the Lewis base.
H2O,OH- have a proton difference of 1 with H2O being an acid and OH- being the Lewis base. So both of them can be considered conjugate acid-base pairs.

- b) Certain cyclic compounds are known to be conformationally similar to carbohydrates, although they are not themselves carbohydrates. One example is Compound C shown below, which could be imagined as adopting four possible conformations. In reality, however, only one of these is particularly stable. Circle the conformation you expect to be the most stable, and provide an explanation to justify your choice. For your explanation to be both convincing and correct, it must contain not only words, but also "cartoon" orbital drawings contrasting the four structures.
