How would you use a Grignard reaction of an aldehyde or ketone to synthesize 2-pentanol?

Draw the Grignard reagent and the aldehyde or ketone you would use below.

Answer :

You start from butanal which will react with methyl magnesium bromide (Gringard reagent) forming a compound with a new carbon-carbon bond. After that using an acid media the magnesium bromide salt is eliminated with formation of the 2-pentanol.
