Hello students, alkanes are simple hydrocarbons containing t and h atom in the form cnh 2n plus 2.
00:13
The intermolecular forces of attraction between molecules of alkanes is negligible.
00:20
For example, two molecules of ethan are not strongly attracted towards each other as there is no electro -negativity differences.
00:30
Hence, they exist as separate molecules.
00:37
The existence as separate molecules are the properties of gas.
00:44
Hence most of the alkanes exist as gas at room temperature.
00:49
In alcohols, whose formula is cnh 2n plus 2o.
00:59
The two molecules of alcohols are strongly attracted towards each.
01:04
Other.
01:05
For example, ethanol.
01:12
Two molecules of ethanol in a system forms hydrogen bond, due to which they are strongly attracted and are placed close to each other to form liquids...
