Question

Assertion: Geometrical isomerism is also called $cis-trans$ isomerism.
Reason: Tetrahedral complexes show geometrical isomerism.

• A. both the assertion and the reason are true and the reason is a correct explanation of the assertion.
• B. both the assertion and reason are true but the reason is not a correct explanation of the assertion
  
• C. assertion is true but the reason is false
• D. assertion is false but reason is true

Answer 1

The correct option is C assertion is true but the reason is false

Geometrical isomerism is also called $cis-trans$ isomerism and Tetrahedral complexes do not show geometrical isomerism because the relative position of the atoms with respect to each other will be the same. So Assertion is true but reason is false.
