The correct reaction/reaction sequence that would produce a dicarboxylic acid as the major product is
(A)(see structure)
(B)(see structure)
(C)(see structure)✓ Correct
(D)(see structure)
Answer: (C)
Solution
To produce a dicarboxylic acid, we need oxidation of both terminal positions of a carbon chain.
Option (C) shows the correct sequence: the starting material undergoes ozonolysis followed by oxidative workup, which cleaves the double bond and oxidizes both fragments to carboxylic acids, yielding a dicarboxylic acid as the major product.
The other options either produce monocarboxylic acids or other products that are not dicarboxylic acids.
