Question

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

• A. In addition to the normal oxidation states, the zero oxidation state is also shown by these elements in complexes.
• B. In the highest oxidation states, the transition metal show basic character and form cationic complexes.
• C. In the highest oxidation states of the first five transition element (Sc to Mn), all the 4s and 3d electrons are used for bonding.
• D. Once the $d^5$ configuration is exceeded, the tendency to involve all the 3d electrons in bonding decreases.

Answer 1

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

In highest oxidation states, transition metals form anionic complexes rather than that of cationic complexes.
