a. $XeCl_{4}$ and $XeCl_{2}$:
The common feature between these two compounds is that they both contain xenon (Xe) bonded to chlorine (Cl) atoms. Xenon is a noble gas, and it is typically unreactive. However, in these compounds, xenon forms covalent bonds with chlorine, which is an unusual occurrence for a noble gas.
b. $ICl_{5}$, $TeF_{4}$, $ICl_{3}$, $PCl_{3}$, $SCl_{2}$, $SeO_{2}$:
The common feature among these compounds is that they all contain a central atom (I, Te, I, P, S, Se) bonded to other atoms (Cl, F, Cl, Cl, Cl, O) in a covalent manner. These compounds are examples of molecular compounds, where the central atom forms covalent bonds with the surrounding atoms to achieve a stable electronic configuration.
