Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Concept:
Some metals form metal-metal bonds resulting in dimeric ions.
Step 1: Mercury behavior
Mercury forms Hg$_2^{2+}$ ion (dimeric ion).
Step 2: Structure
Two Hg atoms are bonded together: \[ Hg - Hg \] Conclusion:
Thus, mercury forms dimeric ions.
