Explanation:
It is known that boiling point is the temperature at which vapor pressure of a liquid becomes equal to the atmospheric pressure. In hydrocarbons, more linearly the carbon atoms are attached to each other more will be the boiling point of the compound because of increase in surface area of the compound.
And, more is the branching present in a compound lesser will be its boiling point.
Also, more is the intermolecular strength present in a compound more will be its boiling point. In water, there will be hydrogen bonding due to which there is strong intermolecular forces of attraction in water molecules. Hence, it will have high boiling point.
Thus, we can conclude that given compounds are ranked from lowest to highest boiling point as follows.
Iso-pentane < Pentane < Ehatnol < sodium n-butoxide < water
The ranking of the given compounds from lowest to highest boiling point are Iso-pentane < Pentane < Ehatnol < sodium n-butoxide < water.
Boiling point:
The temperature at which vapor pressure of a liquid is equal to the atmospheric pressure.
In hydrocarbons boiling points depends on two aspects,
- Structure of chain
- Inter-molecular interaction
Linear molecule tend to have more boiling point because the carbon atoms are attached to each other of with more surface area to interact with other molecules.
Branched molecules tend to have less boiling point because of less surface area to interact with other molecules.
Thus, The ranking of the given compounds from lowest to highest boiling point are Iso-pentane < Pentane < Ehatnol < sodium n-butoxide < water.
