Question
Assertion: The tetrahedral complexes can show geometrical isomerism.
Reason: This is because all the four ligands lie at the same distance from central metal atom in a tetrahedral geometry.
Options
If both Assertion and Reason are CORRECT and Reason is the CORRECT explanation of the Assertion.
If both Assertion and Reason are CORRECT but Reason is not the CORRECT explanation of the Assertion.
If Assertion is CORRECT but Reason is INCORRECT.
If Assertion is INCORRECT but Reason is CORRECT.

Solution
If Assertion is INCORRECT but Reason is CORRECT.
Explanation:
The assertion is incorrect because tetrahedral complexes typically do not show geometrical isomerism. This is because, in a tetrahedral geometry, all the ligand positions are equivalent, so no distinct isomers can form.
The reason given is correct in terms of describing the symmetry of a tetrahedral geometry where all four ligands are equidistant from the central metal atom. However, this equidistant arrangement does not lead to geometrical isomerism.
