In context with the transition elements, which of the following statements is incorrect?

Options

  1. AIn addition to the normal oxidation states, the zero oxidation state is also shown by these elements in comple
  2. BIn the highest oxidation states, the transition metal show basic character and form cationic complexes.
  3. CIn the highest oxidation states of the first five transition elements (Sc to Mn), all the 4 s and 3 d electron
  4. DOnce the d^5 configuration is exceeded, the tendency to involve all the 3d electrons in bonding decreases.

Correct answer

B. In the highest oxidation states, the transition metal show basic character and form cationic complexes.

Step-by-step solution

In higher Oxidation states transition elements show acidic nature
