The complete and detailed mechanism of the Robinson annulation reaction given in Equation 18-55 is to be drawn. Concept introduction: A Robinson annulation reaction is a Michael reaction, the conjugate addition of an enolate anion, followed by intramolecular aldol condensation. One of the reactants of a Robinson annulation must be an α, β- unsaturated carbonyl compound with two acidic α -protons. The second must be a ketone or aldehyde with one acidic α -proton

Question

when performing the reaction that involves 2 equivalents of 3-(diethylamino)-phenol and Phthalic anhydride with sulfuric acid and water react to form rhodamine b where the Phthalic anhydride cleaves in acid and how does Excessive Washing (w/ Base) & Subsequent Resonance Structure get affected

Answer 1

Question

Definition Definition Organic compounds that have a carbonyl group, C=O, as their functional group. The carbonyl group in aldehydes is placed at the end of the molecular structure, which means the C=O is attached to one hydrogen atom and an alkyl group or a benzene ring. Just like all the other homologous series in organic chemistry, the naming of aldehydes uses the suffix “-al”. The general molecular formula is C n H 2n O.

Using the general properties of equilibrium constants At a certain temperature, the equilibrium constant K for the following reaction is 1.3 × 10 4: Cl2(g) + CHCl3(g) HCl(g) + CC₁(g) Use this information to complete the following table. Suppose a 16. L reaction vessel is filled with 1.6 mol of HCI and 1.6 mol of CCl4. What can you say about the composition of the mixture in the vessel at equilibrium? There will be very little Cl2 and CHCl3. ☐ x10 There will be very little HCI and CCl4. Neither of the above is true. What is the equilibrium constant for the following reaction? Be sure your answer has the correct number of significant digits. HCl(g)+CC14(g) 12 Cl2(9)+CHCl3(9) K = 0 ☐ What is the equilibrium constant for the following reaction? Be sure your answer has the correct number of significant digits. 2 Cl₂(9)+2CHCl3(9) 2 HCl(9)+2CC₁₁(9) K = ✓ 00. 18 Ar
