Differences Polar and Non Polar Compounds

Polar and non polar compounds
The characteristics of polar compounds:
• soluble in water and other polar solvents
• have the + and poles -, due to
uneven distribution of electrons
-has a lone pair (when the shape of the molecule known) or have different electronegative
Example: alcohol, HCl, PCl3, H2O, N2O5

Polar compounds are described as
The characteristics of non-polar compounds:
• insoluble in water and other polar solvents
• It has no poles and poles + -, due to
uneven distribution of electrons
-do not have a lone pair (if the shape of molecules known) or the same electronegative
Example: Cl2, PCL5, H2, N2
Non-polar compounds are described as
QUANTITATIVE MEASURE OF COVALENT COMPOUNDS Boiling Point
* Polar compounds boiling point higher than the non-polar compounds
• The order of boiling point, hydrogen bonding> dipole-dipole> non-polar non polar or hydrogen bonding> Van der Waals> style london
• When both polar / non polar, the great Mr. boiling point greater
Mr similar to carbon compounds, chain elongated C boiling point> branched chain (round)

DIFFERENCES WITH POLAR NON POLAR COMPOUNDS
POLAR COMPOUNDS
• soluble in water
• Have a pair of free electrons (dissymmetrical shape)
• Ends odd, except for BX3 and PX5
Eg: NH3, PCl3, H2O, HCl, HBr, SO3, N2O5, Cl2O5
NON POLAR COMPOUNDS
• Tdk soluble in water
• Tdk has a lone pair (symmetric form)
• End even
Ex: F2, Cl2, Br2, I2, O2, H2, N2, CH4, SF6, PCL5, BCl3
Which is a higher boiling point?
A. F2 or N2?
2. CH4 or C3H8?
3. H2O or H2S?
4. NH3 or XeF4?
5. HF or HI?
6. PCL5 or PCl3?
7. n-pentane or 2,2-dimethyl propane
