Preparation of alcohols from carbonyl compounds by Grignard reagent.Explain the given reaction with mechanism.
Answers
We can obtain the three types of monohydric alcohols (primary, secondary and tertiary alcohols) by using Grignard reagents and carbonyl compounds. The addition of RMgX on carbonyl compounds, along with hydrolysis gives us alcohols. The Grignard reagent is basically an organometallic compound. Let us look at this reaction in greater detail as it is a very important reaction.
When we allow a solution of an alkyl halide in dry ethyl ether, (C2H5)O to stand overturnings of metallic magnesium, we witness a vigorous reaction. We can see that the solution turns cloud and begins to boil. The magnesium metal gradually disappears. The resulting solution is the Grignard reagent.
The Grignard reagent has the general formula R MgX, and the general name alkyl magnesium halide.
