Question
Which of the following statements accurately describes the stereochemical outcome of the Strecker synthesis of alanine?A.The product is L-alanine.B.The product is D-alanine.C.The product is a mixture of L- and D-alanine.D.Alanine does not contain a stereocenter.Submit
Solution
The correct answer is C. The product is a mixture of L- and D-alanine.
The Strecker synthesis is a method to produce amino acids that involves the reaction of an aldehyde with ammonium chloride in the presence of potassium cyanide. The cyanide ion acts as a nucleophile, causing the formation of a racemic mixture of amino acids. This means that the product will contain equal amounts of both the L- and D- enantiomers of the amino acid. In the case of alanine, both L-alanine and D-alanine will be produced.
