Question

According to Bohr's postulate -

• A. The angular orbital momentum is integral multiple of $\frac{h}{4\pi }$
• B. The angular orbital momentum is integral multiple of $\frac{h}{2\pi }$
• C. The angular orbital momentum is integral multiple of $\frac{h}{\pi }$
• D. The angular orbital momentum is integral multiple of $2\pi h$

Answer 1

The correct option is B The angular orbital momentum is integral multiple of $\frac{h}{2\pi }$

As per Bohr's postulate, the electron revolves around the nucleus only in those orbits for which the angular orbital momentum is an integral multiple of $\frac{h}{2\pi }$, where $h$ is the Planck’s constant.

Hence, option $\left(B\right)$ is the correct answer.
