In a C-O bond the electrons are

• Pulled towards the O

• Pulled towards the C

• Are spread equally between the C and O

In the C-Cl bond electrons are

• Pulled towards the C

• Pulled towards the Cl

• Shared equally between the C and Cl

A polar bond is when

• Electrons are shared equally.

• Electrons are shared unevenly and are mostly around one of the atoms in the bond.

A bond dipole is when there is a

• Polar bond

• Non-polar bond

• A polar molecule

• A non-polar molecule.
