Detection Of Cations

Given below are certain cations. Using inorganic qualitative analysis, arrange them in increasing group number from I to VI.

A.	Al3+	B.	Cu2+
C.	Ba2+	D.	Co2+
E.	Mg2+

Choose the correct answer from the options given below

1.	B, C, A, D, E	2.	E, C, D, B, A
3.	E, A, B, C, D	4.	B, A, D, C, E

Match List-I with List-II:

List-I (Ion)		List-II (Group Number in Cation Analysis)
A.		I.	Group-I
B.		II.	Group-III
C.		III.	Group-IV
D.		IV.	Group-VI

Choose the correct answer from the options given below:
1. A-III, B-II, C-IV, D-I
2. A-III, B-II, C-I, D-IV
3. A-III, B-IV, C-II, D-I
4. A-III, B-IV, C-I, D-II
