NEET Chemistry Functional Group Tests Match the Following Question
Match Column-I with Column-II.
Column-I Column-II (a) Aluminium hydroxide (i) Yellow precipitate of potassium hexanitritocobaltate (III) (b) Calcium oxalate (ii) White gelatinous precipitate in lake test (c) Cobalt ion (iii) White precipitate with ammonium oxalate (d) Strontium ion (iv) Crimson red flame
Choose the correct matching:
a-ii, b-iii, c-i, d-iv
a-i, b-iv, c-ii, d-iii
a-ii, b-iv, c-iii, d-i
a-iv, b-ii, c-i, d-iii
Correct Answer
Detailed Explanation
Aluminium hydroxide forms a white gelatinous precipitate in the lake test (a-ii), Calcium oxalate gives a white precipitate with ammonium oxalate (b-iii), Cobalt ion produces a yellow precipitate of potassium hexanitritocobaltate (III) (c-i), and Strontium ion confirms with a crimson red flame (d-iv).
