How is ethanol prepared by methanal by using Grignard reagent?
The Grignard reagent is used to convert aldehydes into alcohol. It is represented as [CH equiv {C^ – }N{a^ + }]where [R]is the alkyl group and [X]represents the halogen element. The mechanism involved for the conversion of methanal to ethanol is nucleophilic addition reaction as shown below.

How is ethanol prepared from methanal by using grignard reagent – Brainly
Methanal is aldehyde and ethanol is alcohol. To prepare alcohol from carbonyl compounds, Grinard reagent can be used. It forms secondary alcohols with aldehydes. Grinard reagent is an alkyl magnesium halide. Methanal reacts with Grinard reagent to form ethoxymagnesium chloride adduct. Further it reacts with water to give ethanol.

Synthesis of alcohols using Grignard reagents I – Khan Academy
Because the grignard reagent acts as a carbanion (have two lone pair of electrons on a carbon), it is highly reactive and a strong nucleophile. Because of this, if we were to use water as our solvent, which contain hydrogens that are easy to steal by the carbanion, we would lose our grignard reagent and can no longer complete the reaction. By …

How will you prepare ethyl alcohol by using grignard reagent?
A secondary alcohol is produced by treating the Grignard reagent with suitable aldehyde other than formaldehyde (methanal), followed by hydrolysis. For instance, propan-2-ol (isopropyl alcohol) can be prepared by taking methylmagnesium bromide and acetaldehyde (ethanal). CH3MgBr + CH3CHO —> CH3-CH (CH3)-OMgBr.

Grignard Reagents – Chemistry LibreTexts
Grig nard reagents are made by adding the halogenoalkane to small bits of magnesium in a flask containing ethoxyethane (commonly called diethyl ether or just ether). The flask is fitted with a reflux condenser, and the mixture is warmed over a water bath for 20 – 30 minutes.
