Meaning and Definition
A type of chemical bond intermediate in character between a pure covalent bond and a pure ionic bond.
A bond formed between atoms of significantly different electronegativities where the electron pair is shared unequally, but not transferred completely as in an ionic bond. It's often described as having partial ionic character.

- Confusing it with intermolecular dipole-dipole forces.
- Assuming it's a common synonym for any polar molecule.
FAQ
Frequently Asked Questions
Essentially, yes. The term 'semipolar bond' is a synonym for 'polar covalent bond', though it is less frequently used in modern chemistry. Both describe a covalent bond with unequal electron sharing.
Water (H₂O) is a classic example. The bonds between oxygen and hydrogen are semipolar (polar covalent), as oxygen is more electronegative, pulling electron density towards itself and creating partial charges.
In an ionic bond, an electron is completely transferred from one atom to another, forming positive and negative ions. In a semipolar bond, electrons are still shared, but the sharing is highly unequal, resulting in partial positive and negative ends (a dipole) rather than full ions.
The bonding continuum model is now standard. Chemists typically use 'polar covalent bond' to describe the unequal sharing and specify the percent ionic character, making 'semipolar' a somewhat redundant or historical term.
A type of chemical bond intermediate in character between a pure covalent bond and a pure ionic bond.
Semipolar bond is usually academic/technical (chemistry, materials science) in register.
Semipolar bond: in British English it is pronounced /ˌsɛmɪˈpəʊlə bɒnd/, and in American English it is pronounced /ˌsɛmiˈpoʊlɚ bɑːnd/. Tap the audio buttons above to hear it.
Learning
Memory Aids
Mnemonic
Think 'SEMI-polar' – it's HALFWAY between covalent (sharing) and ionic (stealing) bonding, like a compromise in electron sharing.
Conceptual Metaphor
A tug-of-war where one side is significantly stronger than the other, so the rope (electron pair) is much closer to that side, but not completely surrendered.
