Three reactions between a Grignard reagent and a carbonyl compound are given below. Draw the main organic product for each reaction and indicate if H or H– is needed to complete each reaction. (The starting material structures are provided in the answer fields as a starting point for your drawings.)

See Explaination

Explanation:

The Grignard reagent is a highly reactive organomagnesium compound formed by reacting a haloalkane with magnesium in an ether solvent.

Carbonyl compounds are comprised of aldehydes and ketones.

Please kindly check attachment for the step by step solution of the given problem.

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."
