<img class="img-fluid question-image" alt="Solution" src="https://cdn.tardigrade.in/q/nta/c-juqxthjdyen3780j.jpg" /> The reaction of phenyl magnesium bromide on dry ice form a Grignard adduct which upon acid hydrolysis gives benzoic acid. In this reaction the Grignard reagent gets attached to a carbon atom and the oxygen double bond of carbon dioxide. The product we get is benzoic acid.
