Primary/ tertiary amines donot react with Hinsberg's reagent.

Explanation

### Step-by-Step Solution:

1. **Understanding Hinsberg's Reagent**:
- Hinsberg's reagent is benzene sulfonyl chloride (C6H5SO2Cl). It is used to distinguish between primary, secondary, and tertiary amines.

2. **Reactions with Primary Amines**:
- When a primary amine (RNH2) reacts with Hinsberg's reagent, the reaction leads to the formation of a sulfonamide.
- The reaction can be represented as:
