Paper: CSIR NET December 2013 · Subject: Physical Chemistry · Chapter: Quantum Chemistry · Topic: Hydrogen Atom · Marks: 2 · Difficulty: Medium
The most probable value of 'r' for an electron in 1s orbital of hydrogen atom is 46. The angular momentum operator $\hat{L}_y$
(a)$-\frac{\hbar}{i}\left(y\frac{\partial}{\partial z} - z\frac{\partial}{\partial y}\right)$
(b)$\frac{\hbar}{i}\left(z\frac{\partial}{\partial x} - x\frac{\partial}{\partial z}\right)$
(c)$\frac{-i\hbar}{2m}\frac{\partial}{\partial x}$
(d)$\frac{\hbar}{i}\left(z\frac{\partial}{\partial x} - y\frac{\partial}{\partial y}\right)$
