Q. Match List-I with List-II. [table] List-I (Ion) | List-II (Group Number in Cation Analysis) ; A. Co$^{2+}$ | I. Group-I ; B. Mg$^{2+}$ | II. Group-III ; C. Pb$^{2+}$ | III. Group-IV ; D. Al$^{3+}$ | IV. Group-VI [/table] Choose the correct answer from the options given below:
A) A-III, B-IV, C-II, D-I
B) A-III, B-IV, C-I, D-II
C) A-III, B-II, C-IV, D-I
D) A-III, B-II, C-I, D-IV
Explanation
[Solution by Claude - not from source] $Co^{2+}$ is Group IV, $Mg^{2+}$ is Group VI, $Pb^{2+}$ is Group I, $Al^{3+}$ is Group III. So A-III, B-IV, C-I, D-II. Answer (2).
