Nov 20,2020 - Test: Aldol Condensation | 27 Questions MCQ Test has questions of Class 12 preparation. This contains 10 Multiple Choice Questions for Chemical Engineering Test: Condensation (mcq) to study with solutions a complete question bank. Per la realizzazione di questa reazione si possono usare varie basi quali l'idrossido di sodio NaOH, le ammine e l'etilato sodico EtONa. For example, PhCHO on reaction with excess acetic anhydride in presence of sodium acetate followed by acidification gives cinnamic acid (3-phenyl propenoic acid). In this reaction, the carbanion is obtained by the removal of an Alpha hydrogen atom from acid anhydride by carboxylate (anion of the corresponding acid of the acid anhydride). Turbine c. Economiser View Answer Discuss. If the volume of the reaction vessel is suddenly, reduced to 1/4th of the initial volume, the reaction rate, of borax, the following compound is formed. The product then abstracts a proton from the acid to form – aldol type compound. | {{course.flashcardSetCount}} a. drop-wise condensation b. bulk-wise condensation c. film-wise condensation d. none of the above View Answer / Hide Answer Depending upon the behavior of condensate up on the cooled surface, the condensation process are classified into how many distinct modes? How would the condensation coefficient be effected if due to site constraints, it has to be kept at 60 degree to the horizontal? Identify the compounds A and B in the following reaction sequence.
