Concept explainers
Interpretation:
The decreasing order of freezing point from the given aqueous solution is to be determined.
Concept Introduction:
Freezing point depression: The freezing point of the solution varies with the solute concentration.
Decline in the freezing point is huge when solute is an electrolyte than when solute is nonelectrolyte.
van’t Hoff factor, i: it is the ratio between change in in freezing point measured and change in in freezing point calculated. It indicates the total number of ions that are produced.
Molality (m): Molality is the number of moles of solute present in one kilogram of solvent.
Freezing point of a solution decreases with the increase in concentration of the solute in solution.

- 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.
