Grignard reagents and Alkyl lithiates are moisture sensitive. What is the major organic product obtained if the following organometallic compounds come in contact with deuterated water?

The organometallic and alkyl lithiate compounds whose reaction with water is to be investigated are missing from the question and are on the first image of the attached files to this solution.

The answer is a chemical structure and it is drawn and presented in the second attached image to this question.

The Explanation provides further clues.

Explanation:

Reiterated water is heavy water. It is water but instead of the normal hydrogen, it has deuterium (the heavier isotope of Hydrogen, ²H).

The reaction of Grignard Reagent is used to introduce deuterium in a particular position for molecules.

Normally, the introduced Deuterium just takes the position of the -MgBr substituent on the Grignard's reagent. The -MgBr then takes on the remaining -OD substituent as if it were a -OH substituent.

So, the summary of the reaction is

R-MgBr + D₂O ----> R-D + MgBr(OD)

And for the alkyl lithiate too, the Deutrium just substitutes the -Li and the -Li takes on the -OD, just like in the reaction with Grignard's reagent.

R-Li + D₂O -----> R-D + Li(OD)

Hope this Helps!!!
