In a complex compound, central metal ion is
Options
- AArrhenius acid
- BArrhenius base
- CLewis acid
- DLewis base
Correct answer
C. Lewis acid
Step-by-step solution
In a complex compound, the central metal ion accepts one or more electron pairs from the surrounding ligands to form coordinate covalent bonds. According to the Lewis theory of acids and bases, an electron pair acceptor is defined as a Lewis acid, while an electron pair donor is defined as a Lewis base. Therefore, the central metal ion acts as a Lewis acid. Answer: Lewis acid
