Interpretation Introduction
Interpretation:
Considering the base hydrolysis of given ester answer the follwoing questions.
(b) The product which contains labelled oxygen atom
Concept introduction:
The hydrolysis reaction of an ester can be catalyzed in presence of a base that is hydroxide ion. The rate of reaction increase due to the presence of hydroxide ion which can act as better nucleophile than water molecule. Thus substitution of alkoxide group takes place and carboxylic acid formation occur. The general reaction of base hydrolysis of en ester is written as,
Here, the ester molecule contains a labelled oxygen atom

O The phenolate reacts with the epoxide preferentially over the alkyl halide at the less
sterically hindered position. Then, the sterically hindered amine attacks the alkyl chloride.
O The phenolate reacts with the epoxide preferentially over the alkyl halide at the more
sterically hindered position. Then, the sterically hindered amine attacks the alkyl chloride.
D. N. Kursanov, a Russian chemist, proved that the bond that is broken in the hydroxide-ion-promoted hydrolysis of an ester is the acyl C-O bond, rather than the alkyl C - O bond, by studying the hydrolysis of the following ester under basic conditions: a.What products contained the 18O label? b. What product would have contained the 18O label if the alkyl C - O bond had broken?

- 12 Why is ethanal a stronger acid than ethane? CH3-C-H ethanal CH3-CH3 ethane A. The conjugate base of ethanal (enolate ion) is stabilized by resonance; thus, the compulsion of ethanal to lose a H* (forming the enolate) is increased. Ethane's conjugate base is not stabilized. B. The inductive electron withdrawing effect of the C=O in ethanal increases its proclivity to release a H* C. Steric factors make ethanal the stronger acid. D. You can write resonance structures for ethanal (the carbon acid), indicating enhanced stability. Because the carbon acid is more stable, its acid strength is greater.arrow_forwardQuestion 2 a) i) Draw the structure of the product obtained when the following diester X undergoes an intramolecular Dieckmann condensation.
