Wilkinson's catalyst is an effective catalyst for the hydrogenation of alkene and Yaska's complex is an effective catalyst for oxidative addition.
Fe(CO)4 and CpRh(CO) are isolobal fragments [VSE = 16]. Tendency of oxidative addition reaction increases as we move down the group.
As alkenes are soft electron donors and strong π-acceptors. they exhibit a strong trails effect. Therefore, in Zeise's salt. Pt-Cl bond trails to ethylene is longer whereas there in cis positions are shorter.

The correct answer is option 'D': Tendency of the oxidative addition reaction increases as one moves down the group.

Explanation:
Oxidative addition is a reaction in which a metal-ligand bond is broken and a new bond is formed between the metal and another atom or molecule. This process involves the transfer of electrons from the metal to the newly forming bond. The ease of this reaction depends on several factors, including the nature of the metal and the ligands involved.

As we move down a group in the periodic table, the size of the atoms increases. This increase in size leads to a decrease in the effective nuclear charge experienced by the outermost electrons. As a result, the outermost electrons are less tightly held by the nucleus and are more easily available for bonding.

The tendency of a metal to undergo oxidative addition is related to its ability to donate electrons to the newly forming bond. As we move down a group, the ability of the metal to donate electrons increases due to the larger size and decreased effective nuclear charge. This leads to an increase in the tendency of the metal to undergo oxidative addition reactions.

In addition, as we move down a group, the available d orbitals for bonding also increase. This provides more opportunities for the metal to form new bonds and undergo oxidative addition reactions.

Therefore, the tendency of the oxidative addition reaction increases as one moves down the group in the periodic table. This is because the larger size and increased electron-donating ability of the atoms make them more favorable for forming new bonds.
