Predict the major, organic product for the following reaction.

The figure illustrates the structure of a molecule. A 5-carbon alkane chain is depicted as a line structure using 4 zigzag lines. C 2 is single bonded to C H 3 on the upper left and C H 3 on the upper right, each in the form of a line. C 5 is single bonded to M g on the upper right. M g is single bonded to a central C atom on the lower right in the form of a line. The central C atom is double bonded to O below and single bonded to a second O atom on the upper right. The second O atom is single bonded to B r on the lower right.

The figure illustrates the structure of a molecule. A 6-carbon alkane chain is depicted as a line structure using 5 zigzag lines. C 1 is single bonded to O H on the lower left and double bonded to O above. C 3 is single bonded to C H 3 on the upper left and C H 3 on the upper right, each in the form of a line.

Verified step by step guidance

Identify the starting material as a Grignard reagent, which is an organomagnesium compound. In this case, it is a primary alkyl magnesium bromide.

Recognize that the reaction involves the addition of carbon dioxide (CO2) to the Grignard reagent. This is a common reaction to form carboxylic acids.

Understand that the Grignard reagent will act as a nucleophile, attacking the electrophilic carbon in CO2, leading to the formation of a carboxylate intermediate.

After the nucleophilic attack, the intermediate formed is a magnesium carboxylate complex. This intermediate is not stable and will be protonated in the next step.

The final step involves the addition of an acid (H+ quench) to protonate the carboxylate ion, resulting in the formation of the corresponding carboxylic acid as the major organic product.
