Concept explainers
(a)
To determine: The product of the given reaction.
Interpretation: The product of the given reaction is to be stated.
Concept introduction: Ninhydrin reacts with alpha amino acids to give resonance stablised anion known as Ruhemann’s purple accompanied by evolution of carbon dioxide. The side chain of amino acid is lost as an
(b)
To determine: The product of the given reaction.
Interpretation: The product of the given reaction is to be stated.
Concept introduction: Carboxyl benzyl is used to protect the
(c)
To determine: The product of the given reaction.
Interpretation: The product of the given reaction is to be stated.
Concept introduction: Acetic anhydride is commonly used for acylation of amino acids. All sorts of acylating agents can react with amino group of amino acids. Amino acids contain two major functional groups: the amino group and the carboxylate group.
(d)
To determine: The product of the given reaction.
Interpretation: The product of the given reaction is to be stated.
Concept introduction: Acetic anhydride is commonly used for acylation of amino acids. All sorts of acylating agents can react with amino group of amino acids. Amino acids contain two major functional groups: the amino group and the carboxylate group.
(e)
To determine: The product of the given reaction.
Interpretation: The product of the given reaction is to be stated.
Concept introduction: Nucleophilic addition takes place when hydrogen cyanide reacts with aldehyde or
(f)
To determine: The product of the given reaction.
Interpretation: The product of the given reaction is to be stated.
Concept introduction: Nucleophilic addition takes place when hydrogen cyanide reacts with aldehyde or ketones. Hydrogen cyanide attacks the carbonyl group of aldehydes and ketones to form cyanohydrin. It undergoes acidic hydrolysis to give carboxylic acid.
(g)
To determine: The product of the given reaction.
Interpretation: The product of the given reaction is to be stated.
Concept introduction: Carboxylic acids react with bromine and phosphorus tribromide to give
(h)
To determine: The product of the given reaction.
Interpretation: The product of the given reaction is to be stated.
Concept introduction: Carboxylic acids react with bromine and phosphorus tribromide to give
