ALKANES : PROPERTIES

Alkane

            PHYSICAL PROPERTIES OF ALKANES

1) STATE: C1 - C4 = GAS

                    C5 - C17 = COLOURLESS VOLATILE LIQUIDS

                    C18 - ABOVE = WAXY SOLIDS


2) ODOUR : ODOURLESS

3) COLOR : COLORLESS

4) SOLUBILITY : SOLUBLE IN NON-POLAR SOLVENTS

                               INSOLUBLE IN POLAR SOLVENTS

5) BOILING POINT: INCREASE ON INCREASE IN MOLECULAR MASS.

                                    DECREASES ON BRANCHING


CHEMICAL PROPERTIES OF ALKANES

1) HALOGENATION OF ALKANES

 (A) CHLORINATION


 (B) BROMINATION

 BROMINATION IS SAME AS CHLORINATION BUT IT DOESN'T TAKE PLACE AS EASY AS CHLORINATION

 (C) IODINATION


2) COMBUSTION 

 ALKANES BURN IN EXCESS SUPPLY OF AIR TO PRODUCE CARBONDIOXIDE(CO2) AND WATER(H2O)



3) CONTROLLED OXIDATION



4) ISOMERIZATION



5) AROMATIZATION
