Question

Given below are certain cations. Using inorganic qualitative analysis, arrange them in increasing group number from 0 to VI.
A) Al³⁺
B) Cu²⁺
C) Ba²⁺
D) Co²⁺
E) Mg²⁺
Choose the correct answer from the options given below

• A. B, A, D, C, E
• B. B, C, A, D, E
• C. E, C, D, B, A
• D. E, A, B, C, D

Answer 1

The Correct Option is A

Step 1: Assign group numbers based on periodic table positions:

B ($Cu^{2+}$): Group I A ($Al^{3+}$): Group III

D ($Co^{2+}$): Group V C ($Ba^{2+}$): Group II

E ($Mg^{2+}$): Group VI

Step 2: Arrange in increasing group number:

Order: B \(<\) A \(<\) D \(<\) C \(<\) E
