Expert Solution
Answer to Problem 21P
Explanation of Solution
Sugar molecules can be named as D or L sugars according to their most oxidized carbon at the top of the Fisher projection. The absolute configuration of a molecule can be explained using D and L configuration. In D- sugars, the OH group on the bottom chiral center points to the right while in L- sugars, the OH group on the bottom chiral center points to the left. Aldopentose is a five-carbon aldehyde sugar. Xylose, Arabinose and Ribose are few examples.

Sugar molecules can be named as D or L sugars according to their most oxidized carbon at the top of the Fisher projection. The absolute configuration of a molecule can be explained using D and L configuration. In D- sugars, the OH group on the bottom chiral center points to the right while if L-sugars, the OH group on the bottom chiral center points to the left. Aldotetrose is a four-carbon aldehyde sugar.

Expert Solution
Answer to Problem 21P
Explanation of Solution
Alditols are polyols. Alditols can be produced by reducing an aldehyde or a ketone group in a monosaccharide. In this reduction process, an aldehyde group or a ketone group converts into −CH2OH group. Xylitol is an example of an alditol.

Using reaction free energy to predict equilibrium composition
Consider the following equilibrium:
N2 (g) + 3H2 (g) = 2NH3 (g) AG⁰ = -34. KJ
Now suppose a reaction vessel is filled with 8.06 atm of nitrogen (N2) and 2.58 atm of ammonia (NH3) at 106. °C. Answer the following questions about this
system:
?
rise
Under these conditions, will the pressure of N2 tend to rise or fall?
☐ x10
fall
Is it possible to reverse this tendency by adding H₂?
In other words, if you said the pressure of N2 will tend to rise, can that be
changed to a tendency to fall by adding H₂? Similarly, if you said the
pressure of N2 will tend to fall, can that be changed to a tendency to rise
by adding H₂?
If you said the tendency can be reversed in the second question, calculate
the minimum pressure of H₂ needed to reverse it.
