Students have asked these similar questions
a) Put these three common types of carbonyl compound in order of decreasing reactivity
ester amide acid chloride
b) For the least reactive, show the interconversion to its other resonance form:
How does this electron delocalisation make it stable?
c) For the most reactive, draw the mechanism of its undergoing hydrolysis (reaction with H2O):
Why makes this type of carbonyl so reactive to nucleophiles?
In synthesis of benzoic acid with Grignard reagent, benzene is often detected as an impurity. How is benzene formed?
When performing a Grignard reaction it is also very important that the reaction be free from acetone (a chemical we commonly use to clean the glassware). Why must the glassware be free from acetone?
A. Acetone reacts with the diethyl ether causing a side reaction to occur
B. Acetone is a nucleophile that will react with the Grignard reagent
C. Acetone reacts with the bromobenzene
D. Acetone is an electrophile that will react with the Grignard reagent

- This question has multiple parts. Work all the parts to get the most points. The Stork reaction is a condensation reaction between an enamine donor and an α,β-unsaturated carbonyl acceptor. The overall reaction consists of a three-step sequence of formation of an enamine from a ketone, Michael addition to an α,β-unsaturated carbonyl compound, and hydrolysis of the enamine in dilute acid to regenerate the ketone. Consider the Stork reaction between cyclohexanone and propenal.arrow_forwardThis question has multiple parts. Work all the parts to get the most points.
