(a)
Interpretation:
The structural formula of keto form for the given enol form should be drawn.
Concept Introduction:
A carbonyl compound that has a-hydrogen on a-carbon changes its form to enol through resonance. Both the form stays in equilibrium.
a- hydrogen is the hydrogen which attached to a-carbon for a carbonyl compound. a-carbon is carbon adjacent to the carbonyl carbon. If a compound don’t have any a hydrogen is does not undergoes Keto-Enol tautomerism.
(b)
Interpretation:
The structural formula of keto form for the given enol form should be drawn.

OH F CI Brarrow_forwardA 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_forward
