Question:
Which of the following is a Lewis acid?
Which of the following is a Lewis acid?
Show Hint
Lewis Acid = Acceptor, Lewis Base = Donor.
Updated On: Apr 28, 2026
- HCl
- OH
- $H_{2}O$
- $Co^{3+}$
- $NH_{3}$
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Concept
A Lewis acid is an electron-pair acceptor.
Step 2: Meaning
Positively charged ions or electron-deficient molecules act as Lewis acids.
Step 3: Analysis
$Co^{3+}$ is a cation that can accept electron pairs from ligands.
Step 4: Conclusion
$Co^{3+}$ is a Lewis acid. Final Answer: (D)
