NEET Chemistry Functional Group Tests Match the Following Question
Match Column-I with Column-II.
Column-I Column-II (a) PbCl2 + K2CrO4 (i) Yellow precipitate of lead chromate (b) H2SO4 + alcohol (ii) White precipitate of lead sulphate (c) Dil. HCl + PbCl2 (iii) Shining crystals upon cooling (d) Yellow ammonium sulphide + precipitate (iv) Presence of arsenic group
Choose the correct matching:
a-i, b-ii, c-iii, d-iv
a-ii, b-i, c-iv, d-iii
a-iii, b-iv, c-i, d-ii
a-iv, b-iii, c-ii, d-i
Correct Answer
Detailed Explanation
The addition of K2CrO4 to PbCl2 produces a yellow precipitate of lead chromate (i), while the reaction of H2SO4 with alcohol results in a white precipitate of lead sulphate (ii). The presence of PbCl2 can lead to shining crystals upon cooling (iii), and the interaction with yellow ammonium sulphide confirms the presence of the arsenic group (iv).
