Electronegativity 2

Dipole

O = C = O

S- S+ S-

→ Although made up of polar bonds, cancel each other out producing a non - polar molecule.

Dipole moment with same magnitude covalent opposite

REASONING : Because of the molecules are symmetrical, there’s no overall polarity and the electron is stored evenly out in the whole molecule.

Forces acting between molecules :

Van Der Waals

• Temporary Dipole - induced dipole

• Act between all atoms + molecules

Dipole - Dipole Bond

• H - Cl

Hydrogen Bond

• Acts between certain types of molecules

• H2O , NH3
