The interaction between a polar and non-polar moleclues known as

Options

A. Dipole-dipole interaction
B. Dipole-induced dipole interaction
C. Ion-dipole interaction
D. None of these

Explanation

To solve the question regarding the interaction between a polar and a non-polar molecule, we can follow these steps:

### Step 1: Understand the Types of Molecular Interactions
First, we need to understand the different types of interactions that can occur between molecules. The main types include:
- Dipole-dipole interactions
- Dipole-induced dipole interactions
- Ion-dipole interactions
- London dispersion forces

### Step 2: Define Polar and Non-Polar Molecules
- **Polar molecules** have a significant difference in electronegativity between the atoms, leading to a dipole moment (a positive end and a negative end).
- **Non-polar molecules** have an even distribution of electron density, meaning they do not have a dipole moment.

### Step 3: Identify the Interaction Between Polar and Non-Polar Molecules
When a polar molecule approaches a non-polar molecule, the electric field generated by the polar molecule can induce a temporary dipole in the non-polar molecule. This is known as:
- **Dipole-induced dipole interaction**.

### Step 4: Conclusion
Thus, the interaction between a polar and a non-polar molecule is specifically known as a dipole-induced dipole interaction.

### Final Answer:
The interaction between a polar and non-polar molecule is known as **dipole-induced dipole interaction**.
