Arrange the following compounds in decreasing order of dipole moment values Explain the order
(a) `CBr_(4)` , (b) `CHBr_(3)` , (c ) `CH_(2)Br_(2)` , (d) `CH_(3)Br` .

Explanation

To arrange the compounds CBr₄, CHBr₃, CH₂Br₂, and CH₃Br in decreasing order of dipole moment values, we need to analyze the molecular structure and the electronegativity of the atoms involved.

### Step-by-Step Solution:

1. **Understanding Dipole Moment**:
- The dipole moment (\( \mu \)) is a vector quantity that depends on the polarity of the bonds and the geometry of the molecule. A molecule has a dipole moment if there is an uneven distribution of electron density, leading to a positive and negative end.

2. **Analyzing CBr₄ (Carbon Tetrabromide)**:
