Given below are certain basic radicals. Based on inorganic qualitative analysis, arrange them in increasing order of their group number. A. Zn ²⁺ B. Sr ²⁺ C. As ³⁺ D. NH₄ ⁺ E. Cr ³⁺ Choose the correct answer from the options given below.
Options
- AC, D, E, A, B
- BD, C, E, A, B
- CB, A, E, C, D
- DD, C, A, E, B
Correct answer
B. D, C, E, A, B
Step-by-step solution
In inorganic qualitative analysis, the basic radicals are classified into different groups based on their precipitation reactions. The group assignments for the given radicals are: NH₄ ⁺ belongs to Group 0. As ³⁺ belongs to Group II. Cr ³⁺ belongs to Group III. Zn ²⁺ belongs to Group IV. Sr ²⁺ belongs to Group V. Arranging them in increasing order of their group numbers, we get Group 0 This corresponds to the sequence D, C, E, A, B. Answer: D, C, E, A, B
