Which of the following are the limitation of Bohr's model ?

Options

A. If could not explain the intersities of the fine spectron of the spectral lines
B. No justification was given fi=or the principle of the quantization of angular momentum
C. If could not explain why atom should combine to form bond
D. it could not be applied to single electron atom

Explanation

To address the question regarding the limitations of Bohr's model, we will analyze each point systematically:

### Step-by-Step Solution:

1. **Limitation in Explaining Fine Structure of Spectral Lines**:
- Bohr's model is unable to explain the intensity of the fine spectrum of spectral lines. This limitation arises particularly when dealing with atoms or ions that have more than one electron. The model primarily applies to hydrogen-like (single-electron) systems and fails to account for the interactions in multi-electron systems.
- **Conclusion**: This is a limitation of Bohr's model.
