Directions: In the following questions, A statement of Assertion (A) ...
Assertion (A): Complexes of MX6 and MX5L type (X and L are unidentate) do not show geometrical isomerism.

Reason (R): Geometrical isomerism is not shown by complexes of coordination number 6.

Explanation:
Assertion (A): Complexes of MX6 and MX5L type (X and L are unidentate) do not show geometrical isomerism.

Reason (R): Geometrical isomerism is not shown by complexes of coordination number 6.

The given assertion states that complexes of the type MX6 and MX5L (where X and L are unidentate ligands) do not show geometrical isomerism. This means that these complexes cannot exist in two different isomeric forms due to the restricted rotation of ligands around the metal ion.

The reason given for this assertion is that geometrical isomerism is not shown by complexes of coordination number 6. Coordination number refers to the number of ligands attached to the central metal ion in a complex. In complexes with coordination number 6, the ligands are usually arranged in an octahedral geometry around the metal ion. In this arrangement, the ligands occupy the corners of an octahedron, and there is no possibility for geometrical isomerism because the ligands cannot be arranged in different positions due to the fixed geometry of the octahedron.

So, both the assertion and the reason are true. The reason provides a correct explanation for the assertion. Complexes of MX6 and MX5L type do not show geometrical isomerism because of the fixed octahedral geometry in complexes with coordination number 6.

Therefore, option B is the correct answer.

Read the passage given below and answer the following questions:The existence of coordination compounds with the same formula but different arrangements of the ligands was crucial in the development of coordination chemistry. Two or more compounds with the same formula but different arrangements of the atoms are called isomers. Isomers are compounds with the same molecular formula but different structural formulas and do not necessarily share similar properties. There are many different classes of isomers, like stereoisomers, enantiomers, and geometrical isomers. There are two main forms of isomerism: structural isomerism and stereoisomerism. The different chemical formulas in structural isomers are caused either by a difference in what ligands are bonded to the central atoms or how the individual ligands are bonded to the central atoms.The following questions are multiple choice questions. Choose the most appropriate answer:Q. Due to the presence of ambidentate ligands, coordination compounds show isomerism. Palladium complexes of the type [Pd(C6H5)2(SCN)2] and [Pd(C6H5)2(NCS)2] are
