Single Choice

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

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

Solution

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