Question

For the ground state, the electron in the H - atom has an angular momentum = h, according to the simple Bohr model. Angular momentum is a vector and hence there will be infinitely many orbit with the vector pointing in all possible directions. In actually, this is not true,

A
because Bohr's model gives incorrect values of angular momentum.

Solution

The correct option is A because Bohr's model gives incorrect values of angular momentum.
According to Bohr's second postulate of atomic model, angular momentum of revolving electron must be some integral multiple of h2π so the Bohr's model does not give correct value of angular momentum. Hence verified answer is (a).
