Question

Why are ligands called lewis bases while central metal atoms act as lewis acid?

Answer 1

$\huge\mathfrak\red{Hello,}$

$\huge\underline{Answer:}$

Lewis acids as ligands. The ligands are the ions or molecules bound to the central atom/ion in the coordination entity. ... According to me its not compulsory for a ligand to be a Lewis base, as BF3 is a Lewis acid and can act as a ligand by accepting electrons from a metal in vacant orbital of boron.
