Interpretation: A mechanism has to be proposed for the given reaction.
Concept introduction:
Esters encompass a large family of organic compound with broad application in various fields of science and technology.
In Fischer esterification, a
Esters can be simply represented as,
Fischer esterification can be represented as follows,
Mechanism of the reaction is the step-by-step description of the process by which reactants are changed into products.
Curved arrows show the bonds that are formed and the bonds that are broken in a reaction.
Curved arrows used to understand a reaction mechanism.
Electrophile: It is positively charged species which seeks for negative charge and hence accepts pair of electrons from negatively charged species (Nucleophiles) which results in the formation of
Nucleophile: It is negatively charged species which seeks for positive charge and hence donate pair of electrons to positively charged species (electrophiles) which results in the formation of chemical bond.
Acid chlorides are organic compound and they have
Acid chlorides are most often prepared by treating a carboxylic acid with thionyl chloride.

- Write an equation for the reaction of chloroacetic acid (Ka=1.5103) with trimethylamine (Kb=5.9105) . Calculate the equilibrium constant for the reaction. If 0.10 M solutions of these two species are mixed, what will be their concentrations at equilibrium?arrow_forwardWhen the conjugate acid of aniline, C6H5NH3+, reacts with the acetate ion, the following reaction takes place: C6H5NH3+(aq)+CH3COO(aq)C6H5NH2(aq)+CH3COOH(aq) If Kafor C6H5NH3+ is 1.35105 and Kafor CH3COOH is 1.86105 , what is K for the reaction?arrow_forwardDescribe the trends in the physical properties of carboxylic acids, and contrast theirphysical properties with those of their salts.arrow_forward
- Give at least 5 examples of biological compounds having a carboxylic acid functional group and identify the biochemical importance of each compound.arrow_forwardIsoamyl acetate is the common name of the substance most responsible for the characteristic odor of bananas. Write a structural formula for isoamyl acetate, given the information that it is an ester in which the carbonyl group bears a methyl substituent and there is a 3-methylbutyl group attached to one of the oxygens.arrow_forwardUpon completion of a chemical reaction, you find you have a mixture of benzoic acid and ethyl benzoate. Propose a procedure to separate the ethyl benzoate from the mixture. You should look up the structures of benzoic acid and ethyl benzoate.arrow_forward
- Indicate the CORRECT alternative: a) Acid halides react only in the presence of a catalyst. b) The reaction of an acid chloride with an alcohol produces less of an ester than using the Fischer reaction. c) The nucleophilic substitution reaction in acid derivatives occurs through an SN1 mechanism. d) Reduction of an ester with LiAlH4 yields only secondary alcohols. e) Hydrolysis of an amide in an acid medium produces a carboxylic acid and a protonated amine.arrow_forwardWhat is the solubility, the pH, and reaction of carboxylic acids?arrow_forwardWhy are acid/base catalysts required when producing esters from carboxylic acids and amides but not if acyl halides and acid anhydrides are used?arrow_forward
- Why can an acidic organic compound be separated from a neutral (neither basic nor acidic) organic compound?arrow_forwardPrepare CH3COOC2H5, ethyl acetate, using ethyl alcohol. Write the chemical reaction. The pain reliever acetaminophen is produced by reacting 4-aminophenol with acetic anhydride. Outline a synthesis of acetaminophen from 4-aminophenol including any needed inorganic reagents.arrow_forwardWrite structures and describe thephysical properties of carboxylic acidsarrow_forward
