IX. 3. Molecular Polarity p. 198-204
Polar Molecules The bond between atoms with different electronegativities gives rise to a dipole Dipole-dipole bonds are stronger than London Forces
Ex: H-Cl Has dipoles Unbalanced/ asymmetrical Dipole-dipole bond between molecules Polar molecule
Ex: Cl-Cl no dipoles Balanced molecule only London forces present between molecules Non-polar molecule
Other examples: H 2 O BI 3 O 2 CCl 4 CCl 3 H
Boiling & Melting Temperature Ionic highest bp & mp Then if covalent: Polar molecule with a H-bond Polar molecule Higher # of electrons (atomic #)
Ex: N 2 (l) = - 196 C Covalent Non-polar Low mp & bp
O 2 (l) = - 183 C Covalent Non-polar More electrons than N
NO (l) = - 152 C Polar covalent So higher mp & bp than non-polar covalents
clue: think between molecules!

INTERMOLECULAR FORCES. Three types of force can operate between covalent (not ionic) molecules: Dispersion Forces also known as London Forces as Weak.
Thinking (Electro) Negatively Making Sense page 139.
Intermolecular Forces Pages ; Intermolecular Forces Forces of attraction between molecules Forces of attraction between molecules Link.
Covalent network lattices and covalent layer lattice
bond formed by the giving or Ionic Bond bond formed by the giving or taking of electrons.
Polarity of Bonds Molecular Polarity. Equal Pull on Electrons If there is no difference in the electronegativity of the atoms forming a covalent bond,
Sec. 8.5: Electronegativity and Bond Polarity
Electronegativity and Polarity. Describe how electronegativity is used to determine bond type. Compare and contrast polar and nonpolar covalent bonds.
Covalent Carbon always forms 4 bonds Can form both polar and non-polar compounds Being organic means you have carbon Non-electrolytes Molecular.
Polar vs. Non Polar Molecules. Covalent/Molecular Compounds All molecular compounds are either polar or nonpolar.
Y12 Chemistry. Having poles Opposite ends In molecules its respect to charge Covalent bonds can be either polar or non-polar Polarity.
+ Polarity and Intermolecular Forces. + Types of bonds Ionic – transfer of e- from one atom to another Covalent - sharing of e- between atoms a) nonpolar.

IIIIII Molecular Polarity Covalent Bonding. Covalent Bonds involve sharing electrons But Just like in real life, not all sharing Is equal !!!
Covalent Bonds. Form when two or more non-metal atoms SHARE electrons. There is no transfer of electrons.
Polarity Bonds and molecules. Types of bonds Ionic bonds occur when an atom of low ionisation energy loses valence electrons to an atom of high ionisation.
