Question 1 &2
Answer
In coordination compounds metal can accept electron pair from ligand
According to Lewis acid base theory
Electron pair acceptor is called Lewis acid
Electron pair donor is called Lewis base
In coordination compounds, the metal atom is best discribed as Lewis acid and the ligand is best discribed as Lewis base
Thank you ?
All the best.
