Reason: It has a plane of symmetry.

A

if both Assertion and Reason are true and reason is the correct explanation of the assertion.

B

if both assertion and reason are true but reason is not the correct expalanation of the assertion

C

if assertion is true, reason is false

D

The correct Answer is:
To solve the question regarding the assertion and reason provided, we will analyze both statements step by step. ### Step 1: Understanding the Assertion The assertion states that the complex `[Co(NO_2)_3(NH_3)_3]` does not show optical isomerism. - **Optical Isomerism**: This type of isomerism occurs when a compound can exist in two forms that are mirror images of each other, known as enantiomers. For a compound to exhibit optical isomerism, it must lack any planes of symmetry. ### Step 2: Understanding the Reason The reason states that the complex has a plane of symmetry. - **Plane of Symmetry**: A plane of symmetry divides a molecule into two halves that are mirror images of each other. If a molecule has a plane of symmetry, it cannot exhibit optical isomerism because it cannot form non-superimposable mirror images. ### Step 3: Analyzing the Complex Structure To determine if the complex `[Co(NO_2)_3(NH_3)_3]` has a plane of symmetry, we can visualize or draw its structure: 1. **Drawing the Structure**: The cobalt ion (Co) is at the center, surrounded by three nitro groups (NO2) and three ammonia groups (NH3). 2. **Symmetry Consideration**: When we arrange these ligands around the cobalt ion, we can see that the arrangement can be symmetrical. For instance, if we place one NO2 and one NH3 on one side, there will be an identical arrangement on the opposite side. ### Step 4: Conclusion Since the complex has a plane of symmetry, it cannot show optical isomerism. Thus, both the assertion and reason are true, and the reason correctly explains the assertion. ### Final Answer Both the assertion and reason are true, and the reason is the correct explanation for the assertion. ---
