The compound that gives both iodoform and Fehling’s tests is
Options
(a) ethanol
(b) propanone
(c) 2-butanol
(d) ethanal
Correct Answer:
ethanal
Explanation:
CH₃CHO gives test for aldehyde (Fehling’s test) and iodoform test. CH₃CHO + 2Cu²⁺ + 3OH⁻(Fehling’s solution) → CH₃COO⁻ + 2Cu⁺(Red ppt.) + 2H₂O. CH₃CHO + NaOH + I₂ → HCOONa + CHI₃(Iodoform).
