Can a non-polar molecule have polar covalent bonds?

Explanation

### Step-by-Step Solution

1. **Understanding Polar and Non-Polar Molecules**:
- A polar molecule has a net dipole moment due to the presence of polar covalent bonds, where there is an unequal sharing of electrons between atoms with different electronegativities.
- A non-polar molecule has no net dipole moment, meaning that any polar bonds present must cancel each other out.

2. **Identifying Polar Covalent Bonds**:
- Polar covalent bonds occur when two atoms with different electronegativities form a bond. The atom with higher electronegativity attracts the shared electrons more strongly, resulting in a partial negative charge (δ-) on that atom and a partial positive charge (δ+) on the other atom.
