Question

Match the following

• A. A-IV, B-I, C-II, D-V
• B. A-IV, B-II, C-I, D-V
• C. A-III, B-I, C-II, D-V
• D. A-III, B-V, C-I, D-IV

Hint:

Transition metals are groups 3-12. Group 13 elements are the 'Boron family'. Key transition metal groups to remember are 3 (Sc, Y, La), 6 (Cr, Mo, W), 7 (Mn, Tc, Re), and 12 (Zn, Cd, Hg).

Answer 1

The Correct Option is A

Step 1: Identify the group for each set of elements in List-1.
The group numbers in the modern IUPAC periodic table range from 1 to 18.

Step 2: Match set A: Mn, Tc, Re.
Manganese (Mn), Technetium (Tc), and Rhenium (Re) are transition metals. They belong to Group 7 (formerly VIIB).
A matches with IV (7).

Step 3: Match set B: Zn, Cd, Hg.
Zinc (Zn), Cadmium (Cd), and Mercury (Hg) are the last elements of the transition metal block. They belong to Group 12 (formerly IIB).
B matches with I (12).

Step 4: Match set C: Ti, Zr, Hf.
Titanium (Ti), Zirconium (Zr), and Hafnium (Hf) are early transition metals. They belong to Group 4 (formerly IVB).
C matches with II (4).

Step 5: Match set D: Ga, In, Tl.
Gallium (Ga), Indium (In), and Thallium (Tl) are in the p-block and are just after the transition metals. They are the elements of the Boron family. They belong to Group 13 (formerly IIIA).
D matches with V (13).

Step 6: Combine the matches to find the correct option.
A-IV, B-I, C-II, D-V. This corresponds to option (A).
