Which of the following statements are not correct ?

Options

A. If `Delta_(0)ltP`, low spin state is more stable
B. CO is a very weak ligand
C. The colour of a complex depends only on the nature of metal ion
D. Tetrahedral complexes have nearly 50% CFSE value than octahedral complexes

Answer

A, B, C

Explanation

If `P lt Delta_(0)`, low spin state is more stable. Hence, (a) is wrong. CO is a very strong ligand. Hence, (b) is wrong. The colour of the complex depends not only on the metal ion but also on the nature of the ligand. Hence, (c ) is wrong.
