Match List I with List II and select the correct option.
List I | List II |
|---|---|
(P) CH₃CHO & PhCHO | (1) Br₂/H₂O test |
(Q) CH₃CH₃ & HC≡CH | (2) Ammoniacal AgNO₃ test |
(R) CH₃C≡CH & CH₃COCH₃ | (3) Iodoform test |
(S) CH₃CHO & CH₃COCH₃ | (4) NaHSO₃ test |
| (5) Fehling test |
Options:
Answer:
A
Solution:
P: acetaldehyde gives iodoform and Fehling tests; benzaldehyde does not. Q: acetylene decolourises bromine water and forms silver acetylide; ethane does neither. R: propyne gives bromine-water and silver-acetylide tests; acetone gives iodoform and bisulphite-adduct tests. S: both carbonyls give iodoform/bisulphite tests, but only acetaldehyde gives ammoniacal-silver and Fehling tests. Entry 2 is interpreted as ammoniacal . Correct matching option: A.
