Show the polarisation of carbon-magnesium bond in the following structure.
` CH_3 - CH_2 - CH_2 - Mg - X`

Explanation

To show the polarization of the carbon-magnesium bond in the structure `CH₃ - CH₂ - CH₂ - Mg - X`, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Components of the Structure**:
- The structure consists of a carbon chain (CH₃ - CH₂ - CH₂) attached to a magnesium (Mg) atom, which is further connected to a halogen (X).

2. **Understand the Nature of Magnesium**:
