According to Bohr's theory which one of the following values of angular momentum of hydrogen atom is not permitted?
$\frac{1.25 h}{\pi}$
$\frac{h}{\pi}$
$\frac{1.5 h}{\pi}$
$\frac{0.5 h}{\pi}$
Solution
According to Bohr's model, electrons revolve only in those orbits for which angular momentum is an integral multiple of $\frac{h}{2 \pi}$ i.e., $m v r=\frac{n h}{2 \pi}$
