- A-III, B-IV, C-I, D-II
- A-I, B-II, C-III, D-IV
- A-IV, B-I, C-II, D-III
Answer
(1) A-II, B-III, C-IV, D-I
Solution
(A): an unsaturated compound (C=C / C≡C) adds Br2, so the reddish orange colour of bromine water disappears; hence (A) is II.
(B): an alcohol forms a red complex with ceric ammonium nitrate, so (B) is III.
(C): a phenol gives a blue, green, violet or red colour with neutral FeCl3, so (C) is IV.
(D): an aldehyde or ketone gives a yellow, orange or red 2,4-dinitrophenylhydrazone precipitate, so (D) is I.
Hence A-II, B-III, C-IV, D-I.
Answer: (1)
