Bohr's model of the structure of atom is not in conformity with

Options

A. Heisenberg's uncertainty principle
B. Hund's rule of maximum multiplicity
C. Aulbau principle
D. Paulis exclusion principle

Explanation

To solve the question regarding Bohr's model of the structure of the atom and its conformity with various principles, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Bohr's Model**:
- Bohr's model posits that electrons orbit the nucleus at specific distances and with definite velocities. This means that the position of the electron can be precisely determined.

2. **Identify Relevant Principles**:
- The question asks which principle is not in conformity with Bohr's model. We need to consider principles related to electron behavior and positioning, such as:
- Hund's Rule of Maximum Multiplicity
- Pauli's Exclusion Principle
- Heisenberg's Uncertainty Principle

3. **Analyze Each Principle**:
- **Hund's Rule**: This rule deals with the distribution of electrons in orbitals of the same energy level. It does not contradict Bohr’s model.
- **Pauli's Exclusion Principle**: This principle states that no two electrons can have the same set of quantum numbers. It also does not contradict Bohr's model.
- **Heisenberg's Uncertainty Principle**: This principle states that it is impossible to know both the exact position and momentum of an electron simultaneously. This directly contradicts Bohr's model, which assumes that both can be known precisely.

4. **Conclusion**:
- Since Bohr's model assumes precise knowledge of an electron's position and velocity, it is not in conformity with the Heisenberg's Uncertainty Principle.

### Final Answer:
Bohr's model of the structure of the atom is not in conformity with **Heisenberg's Uncertainty Principle**.
