Statement I: Tetrahedral complexes do not show geometrical isomerism

Statement II: The relative positions of the ligands in the tetrahedral complex are adjacent to each other

Both Statement I and statement II are correct and statement II is the correct explanation of statement I

The correct answer is option 1. Both Statement I and Statement II are correct, and Statement II is the correct explanation of Statement I.

Statement I: Tetrahedral complexes do not show geometrical isomerism.

Statement II: The relative positions of the ligands in the tetrahedral complex are adjacent to each other.

Both statements are correct:

Statement I is true. Tetrahedral complexes do not exhibit geometrical isomerism. Geometrical isomerism occurs in coordination complexes when ligands can be arranged differently around the central metal ion, leading to different isomers with the same molecular formula but different spatial arrangements. However, in tetrahedral complexes, the ligands are arranged in such a way that geometric isomers cannot be formed. The ligands are located at the corners of a tetrahedron, and there is no possibility for different spatial arrangements with the same ligands.

Statement II is also correct. In a tetrahedral complex, the relative positions of the ligands are adjacent to each other. The ligands are situated at the corners of a tetrahedron, and each ligand is bonded directly to the central metal ion, making them adjacent.

Statement II provides the correct explanation for why tetrahedral complexes do not exhibit geometrical isomerism. The spatial arrangement of ligands in a tetrahedral complex does not allow for different geometric isomers to be formed.
