Question

Arrange the following II B (or 12) group elements in the increasing order of their Pauling electronegativities:
Elements:
A. Zn
B. Hg
C. Cd
Choose the correct answer from the options given below:

• A. (A), (B), (C)
• B. (C), (B), (A)
• C. (C), (A), (B)
• D. (A), (C), (B)

Hint:

Electronegativity increases as you move to the right in the periodic table or from heavier to lighter elements within a group.

Answer 1

The Correct Option is D

The electronegativities of group 12 elements are as follows:
• Zinc (Zn): 1.65
• Cadmium (Cd): 1.69
• Mercury (Hg): 2.00
Thus, the increasing order of their electronegativities is \(Zn < Cd < Hg\).
