Aldehyde having no α hydrogen cannot undergo aldol condensation. By the shown figure there is no α−H present in trichloroethanal and benzaldehyde . Write chemical tests to distinguish between the following pairs. a. Pent −2− one and pent −3− one b. Propanal and benzaldehyde c. Ethanol and ethanoic acid. Assertion : Benzaldehyde gives a positive test with Benedict's and Fehling's solution. Reason: Benzaldehyde gives silver mirror with Tollen's reagent. Assertion : Benzaldehyde gives a positive test with Benedict's and Fehling's solution. Reason: Benzaldehyde gives silver mirror with Tollen's reagent.
