Concept explainers
(a)
Interpretation: The labeled phase diagram for the given
Concept introduction: The azeotropic mixture is defined as a mixture of two or more liquids which evaporates without altering the composition of the mixture. The azeotropic mixture has a constant boiling point because of the same composition in liquid as well as vapor phase. The components of azeotropic mixture are not separated by distillation processes.
The phase diagram represents the changes in the mixture on changing the conditions like temperature and pressure of the mixture.
(b)
Interpretation: The cooling curve for a mixture of composition
Concept introduction: The azeotropic mixture is defined as a mixture of two or more liquids which evaporates without altering the composition of the mixture. The azeotropic mixture has a constant boiling point because of the same composition in liquid as well as vapor phase. The components of azeotropic mixture are not separated by distillation processes.
The cooling curve is a graphical representation of change of phase of compound. It is plotted between temperature and time.

- Where are the chiral centers in this molecule? Also is this compound meso yes or no?arrow_forwardA 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. Eliminate unnecessary peaks from Gas Chromatography results.arrow_forwardIs the molecule chiral, meso, or achiral? CI .CH3 H₂C CIarrow_forward
- A mixture of three compounds Phen-A, Acet-B and Rin-C was analyzed using TLC with 1:9 ethanol: hexane as the mobile phase. The TLC plate showed three spots of R, 0.1 and 0.2 and 0.3. Which of the three compounds (Phen-A; Acet-B or Rin-C) would have the highest (Blank 1), middle (Blank 2) and lowest (Blank 3) spot respectively? 0 CH: 0 CH, 0 H.C OH H.CN OH Acet-B Rin-C phen-A A A <arrow_forwardHow many chiral carbons are in the molecule?
