Which of the following is called mandelonitrile?
Mandelonitrile is the name for benzaldehyde cyanohydrin. Mandelonitrile is the cyanohydrin derivative of benzaldehyde or the nitrite of mandelic acid.
How do you make mandelonitrile?
The mandelonitrile can be prepared by the action of hydrocyanic acid on benzaldehyde,3 and by the action of sodium or potassium cyanide on the sodium bisulfite addition product of benzaldehyde.
Which cyanohydrin is also called mandelonitrile?
benzaldehyde
In organic chemistry, mandelonitrile is the nitrile of mandelic acid, or the cyanohydrin derivative of benzaldehyde.

What is the functional group of mandelic acid?
A 2-hydroxy monocarboxylic acid that is acetic acid in which two of the methyl hydrogens are substituted by phenyl and hydroxyl groups. Mandelic acid is an aromatic alpha hydroxy acid with the molecular formula C6H5CH(OH)CO2H.
Do aldehydes react with nahso3?
Aldehydes react with sodium bisulphite (sodium hydrogen sulphite) to give addition products. Ketones, except for methyl ketones, do not react with sodium bisulphite due to steric hinderance (crowding).
What is the pH level of mandelic acid?
between 3-4
With mandelic acid, the pH needs to be between 3-4 in be effective. Anything higher than 4.5 will decrease the efficacy.
What can mandelonitrile be used as an intermediate for?
The naturally occurring ( R )- (+) enantiomer finds use as an intermediate in the preparation of optically active α-hydroxy carboxylic acids, α-hydroxy aldehydes, α-hydroxy ketones, and 2-amino alcohols. Mandelonitrile can break down into cyanide and benzaldehyde, a reaction that can be catalyzed by the enzyme mandelonitrile lyase .
Which is a product of the enzyme mandelonitrile?
hydrogen cyanide + benzaldehyde Hence, this enzyme has one substrate, mandelonitrile, and two products, hydrogen cyanide and benzaldehyde. This enzyme belongs to the family of lyases, specifically the aldehyde-lyases, which cleave carbon-carbon bonds.
Where does the nitrile of mandelic acid occur?
From Wikipedia, the free encyclopedia In organic chemistry, mandelonitrile is the nitrile of mandelic acid, or the cyanohydrin derivative of benzaldehyde. Small amounts of mandelonitrile occur in the pits of some fruits.
What are the substrates of mandelonitrile benzaldehyde lyase?
Hence, this enzyme has one substrate, mandelonitrile, and two products, hydrogen cyanide and benzaldehyde . This enzyme belongs to the family of lyases, specifically the aldehyde-lyases, which cleave carbon-carbon bonds. The systematic name of this enzyme class is mandelonitrile benzaldehyde-lyase (hydrogen cyanide-forming).
