CHBrCIF has `"chiral" // "achiral"` carbon atom.

Explanation

To determine whether the carbon atom in CHBrClF is chiral or achiral, we need to analyze its structure and the characteristics of chirality. Here’s a step-by-step solution:

### Step 1: Identify the Carbon Atom
In the compound CHBrClF, we have a carbon atom that is bonded to four different substituents:
- A hydrogen atom (H)
- A bromine atom (Br)
- A chlorine atom (Cl)
- A fluorine atom (F)
