Question

Identify the orbital which has lobes not orienting on the axis

• A. \(p_x\)
• B. \(p_y\)
• C. \(d_{x^2-y^2}\)
• D. \(d_{yz}\)

Hint:

A simple mnemonic for d-orbitals: if the subscript has two different letters (like xy, yz, xz), the lobes are *between* those axes. If the subscript involves squares (like \(x^2-y^2\), \(z^2\)), the lobes are *on* the axes.

Answer 1

The Correct Option is D

Step 1: Understanding the Question:
Which orbital has lobes not on axes?

Step 2: Key Concept (Alternate):
p orbitals lie along axes. d_xy, d_yz, d_xz lie between axes at 45°.

Step 3: Detailed Explanation:
p_x on x-axis. p_y on y-axis. d_x²-y² lobes on x,y axes. d_yz lobes between y and z axes.

Step 4: Final Answer:
d_yz has lobes not orienting on axes.
