Concept explainers
(a)
Interpretation:
The entropy of the system increases or decreases for the given process has to be predicted.
Concept Introduction:
The randomness present in the system is called its entropy. It is an extensive property. At equilibrium, the entropy of the system is zero. The entropy that is measured under the standard conditions of temperature is known as standard entropy. The entropy for one mole of the substance under standard conditions is called standard molar entropy.
(b)
Interpretation:
The entropy of the system increases or decreases for the given process has to be predicted.
Concept Introduction:
Same as part (a).
(c)
Interpretation:
The entropy of the system increases or decreases for the given process has to be predicted.
Concept Introduction:
Same as part (a).

- Q5: Label each chiral carbon in the following molecules as R or S. Make sure the stereocenter to which each of your R/S assignments belong is perfectly clear to the grader. (8pts) R OCH 3 CI H S 2pts for each R/S HO R H !!! I OH CI HN CI R Harrow_forwardCalculate the proton and carbon chemical shifts for this structurearrow_forwardA. B. b. Now consider the two bicyclic molecules A. and B. Note that A. is a dianion and B. is a neutral molecule. One of these molecules is a highly reactive compound first characterized in frozen noble gas matrices, that self-reacts rapidly at temperatures above liquid nitrogen temperature. The other compound was isolated at room temperature in the early 1960s, and is a stable ligand used in organometallic chemistry. Which molecule is the more stable molecule, and why?arrow_forward
- A mixture of C7H12O2, C9H9OCl, biphenyl and acetone was put together in a gas chromatography tube. Please decide from the GC resutls which correspond to the peak for C7,C9 and biphenyl and explain the reasoning based on GC results.
