Concept explainers
(a)
Interpretation:
The product obtained in skraup synthesis by replacing aniline with para-ethylaniline has to be given.
Concept Introduction:
Skraup synthesis is the reaction of aniline with an alpha-beta unsaturated carbonyl compound and proceeds through the formation of carbocation and results in the formation of cyclic ring which on reduction gives quinoline.
(b)
Interpretation: The product obtained in skraup synthesis by replacing glycerol with 3-hexen-2-one has to be given.
Concept Introduction:
Skraup synthesis is the reaction of aniline with an alpha-beta unsaturated carbonyl compound and proceeds through the formation of carbocation and results in the formation of cyclic ring which on reduction gives quinoline.
(c)
Interpretation: The reactants required for the preparation of 2,7-diethyl-3-methylquinoline in skraup synthesis should be given.
Concept Introduction:
Skraup synthesis is the reaction of aniline with an alpha-beta unsaturated carbonyl compound and proceeds through the formation of carbocation and results in the formation of cyclic ring which on reduction gives quinoline.

- 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. Eliminate unnecessary peaks from Gas Chromatography results.arrow_forwardIs the molecule chiral, meso, or achiral? CI .CH3 H₂C CIarrow_forwardPLEASE HELP ! URGENT!arrow_forward
