In context with the transition elements, which of the following statem...

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

Explanation:
Transition elements are the elements that have partially filled d orbitals in their ground state or in any of their oxidation states. They exhibit a wide range of oxidation states and form various types of complexes. Let us analyze each option to identify the incorrect statement.

a) In the highest oxidation states, the transition metal show basic character and form cationic complexes:
This statement is incorrect. Transition metals do not show basic character in their highest oxidation states. In fact, they tend to show acidic or amphoteric character in their highest oxidation states. For example, in the highest oxidation state, manganese forms permanganate ion (MnO4-) which is acidic in nature and forms acidic solutions. Similarly, chromium forms chromate ion (CrO42-) and dichromate ion (Cr2O72-) which are also acidic in nature. Therefore, the statement is incorrect.

b) In the highest oxidation states of the first five transition elements (Sc to Mn), all the 4s and electrons are used for bonding:
This statement is correct. In the highest oxidation states of the first five transition elements, all the 4s and electrons are used for bonding. For example, in the highest oxidation state of manganese (Mn), the electronic configuration is 3d0 4s0, and all the 4s and electrons are used for bonding.

c) Once the d5 configuration is exceeded, the tendency to involve all the 3d electrons in bonding decreases:
This statement is correct. Once the d5 configuration is exceeded, the tendency to involve all the 3d electrons in bonding decreases. This is because the 3d orbitals can accommodate a maximum of 10 electrons. When the d5 configuration is exceeded, the additional electrons go to the higher energy 4s and 4p orbitals, rather than pairing up in the 3d orbitals.

d) In addition to the normal oxidation states, the zero oxidation state is also shown by these elements in complexes:
This statement is correct. In addition to the normal oxidation states, the transition elements can also show zero oxidation state in complexes. For example, in the complex formed between platinum and carbon monoxide, [Pt(CO)4]2-, platinum has a zero oxidation state.

Therefore, the correct answer is option A, as the statement "In the highest oxidation states, the transition metal show basic character and form cationic complexes" is incorrect.

Read the passage given below and answer the following questions:Within the 3d series, manganese exhibits oxidation states in aqueous solution from +2 to +7, ranging from Mn2+(aq) to MnO−4 (aq). Likewise, iron forms both Fe2+(aq) and Fe3+(aq) as well as the FeO2−4 ion. Cr and Mn form oxyions CrO2−4, MnO−4, owing to their willingness to form multiple bonds. The pattern with the early transition metals—in the 3d series up to Mn, and for the 4d, 5d metals up to Ru and Os—is that the maximum oxidation state corresponds to the number of ‘‘outer shell’’ electrons. The highest oxidation states of the 3d metals may depend upon complex formation (e.g., the stabilization of Co3+ by ammoni

Read the passage given below and answer the following questions:The transition metals when exposed to oxygen at low and intermediate temperatures form thin, protective oxide films of up to some thousands of Angstroms in thickness. Transition metal oxides lie between the extremes of ionic and covalent binary compounds formed by elements from the left or right side of the periodic table. They range from metallic to semiconducting and deviate by both large and small degrees from stoichiometry. Since d-electron bonding levels are involved, the cations-exist in various valence states and hence give rise to a large number of oxides. The crystal structures are often classified by considering a cubic or hexagonal close-packed lattice of one set of ions with the other set of ions filling the octahedral or tetrahedral interstices. The actual oxide structures, however, generally show departures from such regular arrays due in part to distortions caused by packing of ions of different size and to ligand field effects. These distortions depend not only on the number of d-electrons but also on the valence and the position of the transition metal in a period or group.In the following questions, a statement of assertion followed by a statement of reason is given.
