Question

Orbital angular momentum of an electron present in $3d_{xy}$ orbital is:

• A. $\sqrt{6}h$
• B. $\sqrt{6}\frac{h}{2\pi }$
• C. $\sqrt{6}\frac{h}{4\pi }$
• D. Both (a) and (b)

Answer 1

The correct option is B $\sqrt{6}\frac{h}{2\pi }$

$3d_{xy}$ orbital is given, here $l=2$
$\therefore$ orbital angular momentum $L=\sqrt{l(l+1)}\frac{h}{2\pi }=\sqrt{6}\frac{h}{2\pi }$
