Answer:

See explanation and image attached

Explanation:

A Grignard reagent is an alkyl magnesium halide. If it reacts with ethyl formate, an intermediate is formed as shown.

This intermediate can undergo water hydrolysis to form a diol, ethanol and MgBrOH.

Oxidation of the diol obtained now yields the corresponding alkanal which in this case is ethanal.

The scheme of the reaction is shown in the image attached to this answer.
