How does electronegativity affect covalent bonds?
- In a covalent bond between two atoms of different electronegativities, the bonding electrons will be drawn towards the more electronegative atom making the bond polar
- If the electronegativities of two atoms are similar then the bonds between them are essentially non polar
- The greater the difference in electronegativity between atoms the more polar the bond
- The difference in electronegativity in the polar bond causes a permanent dipole
