Intermolecular force present in nylon-6, 6 is

Options

A. van der Waal
B. Hydrogen bond
C. Sulphide linkage
D. Dipole-dipole interactions

Answer

To determine the intermolecular forces present in nylon 6,6, we will follow these steps:

### Step 1: Understand the Structure of Nylon 6,6
Nylon 6,6 is a type of polyamide formed from hexamethylenediamine and adipic acid. The repeating units consist of amine (NH2) and carboxylic acid (COOH) functional groups.

### Step 2: Identify Functional Groups
In nylon 6,6, we have:
- Amine group (NH2)
- Carboxylic acid group (COOH)

These functional groups are crucial in determining the type of intermolecular forces present.

### Step 3: Analyze Possible Intermolecular Forces
The options given are:
1. Van der Waals forces
2. Hydrogen bonds
3. Sulfide linkages
4. Dipole-dipole interactions

We will analyze each option:
- **Van der Waals forces**: These are weak forces and are not the primary interactions in nylon 6,6.
- **Hydrogen bonds**: These occur between the hydrogen atom of the amine group and the electronegative atom (like oxygen) in the carboxylic group. This is a strong interaction and is likely present in nylon 6,6.
- **Sulfide linkages**: These involve sulfur atoms and are not relevant to nylon 6,6.
- **Dipole-dipole interactions**: While there are polar bonds, the significant interaction in nylon 6,6 is due to hydrogen bonding rather than dipole-dipole interactions.

### Step 4: Conclusion
Based on the analysis, the predominant intermolecular force present in nylon 6,6 is hydrogen bonding.

### Final Answer
The intermolecular force present in nylon 6,6 is **hydrogen bonding**.
