Benzaldehyde: How are the following compounds obtained from

How are the following compounds obtained from benzoic acid? a) Ethyl benzoate b) Benzyl alcohol c) Benzene. 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. Aldehyde having no α hydrogen cannot undergo aldol condensation. By the shown figure there is no α−H present in trichloroethanal and benzaldehyde .
