Question

Given an example of cyanohydrin reaction.

Answer 1

We need to know that in organic chemistry, hydrocarbons are an important topic. The hydrocarbons are majorly classified as three groups. There are alkane, alkene and alkyne. The alkane means carbon-carbon single bond. The alkene has a carbon-carbon double bond. The alkyne means carbon-carbon having triple bond in the molecule. The IUPAC has certain rules and regulations for the naming of the organic compound. In that method only we named the organic molecules in World level. The naming of any organic molecule depends on the parent saturated hydrocarbon.

Complete answer:
As we know that cyanohydrin is one of the organic compounds. The chemical formula of cyanohydrin is . Here R and R’ is nothing but an alkyl or allyl group.
When aldehyde and ketones are reacted with hydrogen cyanide in the presence of excess sodium cyanide to produce cyanohydrin. This kind of reaction is called cyanohydrin reaction.
But naturally cyanohydrin is not a final product, it is one of the intermediate in the chemical reaction.
For example,
The chemical equation for the cyanohydrin reaction is given below,
$RR'C = O + HCN \to RR'C\left( {OH} \right)CN$
According to the above discussion and equation, we conclude the above reaction is an example of cyanohydrin reaction.

Note:
We have to know the conversion of one type of hydrocarbon to another hydrocarbon by oxidation and reduction. The oxidation of alkane to give alkene. The oxidation of alkene to give alkyne. The reduction of alkyne to give alkene. The reduction of alkene to give alkane. It has some general formulas. The general formula of alkane is ${{\text{C}}_{\text{n}}}{{\text{H}}_{{\text{2n + 2}}}}$. The general formula of alkene is ${{\text{C}}_{\text{n}}}{{\text{H}}_{{\text{2n}}}}$. The general formula of alkyne is ${{\text{C}}_{\text{n}}}{{\text{H}}_{{\text{2n - 2}}}}$. The oxidation means the addition of oxygen or removal of hydrogen or the loss of electrons in the reactant in chemical reaction. The reduction means the removal of hydrogen or the addition of oxygen or the gain of electrons in the chemical reaction.
