The correct Answer is:
To analyze the given assertion and reason, we will break down each statement step by step. ### Step 1: Understand the Assertion The assertion states that the `3d_(z^2)` orbital is spherically symmetrical. **Analysis**: - The `3d_(z^2)` orbital, also known as the d-z squared orbital, has a distinct shape that is not spherical. It has a "doughnut" shape around the z-axis and a lobe extending along the z-axis. Therefore, this assertion is **false**. ### Step 2: Understand the Reason The reason states that the shapes of all five d-orbitals are similar to each other. **Analysis**: - The five d-orbitals are: 1. `d_(xy)` 2. `d_(yz)` 3. `d_(zx)` 4. `d_(x^2 - y^2)` 5. `d_(z^2)` - Each of these orbitals has a unique shape. For example, the `d_(xy)`, `d_(yz)`, and `d_(zx)` orbitals have a cloverleaf shape, while the `d_(z^2)` orbital has a different shape with a lobe along the z-axis and a torus around the equator. Therefore, the reason is also **false**. ### Step 3: Conclusion Since both the assertion and the reason are false, the correct answer to the question is that both statements are incorrect. ### Final Answer Both the assertion and the reason are false. ---
