JEE Main levelSingle correct optionDifficulty 2 of 3cc139

Assertion: tetrahedral does not show geometrical isomerism. Reason: in a tetrahedron every ligand position is adjacent to every other position, so there are no distinct cis and trans arrangements.

  1. ABoth Assertion and Reason are true and the Reason is the correct explanation of the Assertion
  2. BBoth Assertion and Reason are true but the Reason is not the correct explanation of the Assertion
  3. CAssertion is true but Reason is false
  4. DAssertion is false but Reason is true

Answer: A

In a tetrahedron each of the four positions makes the same angle with the other three, so any arrangement is identical to every other. The Assertion is true and the Reason is exactly why it is true.
