Question
Molecules:
- Have covalent bonds and are always polar
- Have covalent bonds and are always nonpolar
- Have covalent bonds and can be polar or nonpolar
- Have ionic bonds and are always polar
Hint:
Polarity depends on electronegativity, not on the type of bonds.
The correct answer is: Have covalent bonds and can be polar or nonpolar
- Covalent bonds are formed by sharing a pair of electrons.
- Polarity depends on the electronegativity of the atoms.
- Molecules having covalent bonds can be polar or non-polar.
