Question
How the benzaldehyde and acetaldehyde are differentiated?
✓

Answer

(i) Benzaldehyde $\left( C _6 H _5 CHO \right)$ does not gives iodoform test while acetaldehyde $\left( CH _3 CHO \right)$ gives iodoform test.
(ii) $C _6 H _5 CHO$ does not reacts with Fehling solution while Fehling solution is reduced by $CH _3 CHO$.
