Which of the following does not give Fehling solution test?

Question

Which of the following does not give Fehling solution test? (A) Acetone (B) Propanal (C) Ethanal (D) Butanal

Tardigrade Admin · Accepted Answer

Fehling solution is cupric ion complex with tartarate anion. Aldehydes reduce it to red precipitate. The red precipitate is chemically Cu2O <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/b14d25030549e3d1ecab8319a4829cc3-.png" /> ∴ Only acet one which is ketone not an aldehyde does not give iodoform test.

Fehling solution is cupric ion complex with tartarate anion. Aldehydes reduce it to red precipitate. The red precipitate is chemically $C u_{2} O$

$∴$ Only acet one which is ketone not an aldehyde does not give iodoform test.
