well well well i was asking for the answer..??
Since Heptane has a boiling point of 98 degrees Celsius, and Heptanol has a boiling point of 176 degrees Celsius, you'd evaporate or boil the Heptane and Heptanol mixture to around 120 degrees Celsius. Which would leave the Heptanol behind and have the Heptane evaporated.
The C7H16 isomer with the highest boiling point is heptane. This is because heptane has a linear structure with stronger London dispersion forces compared to its branched isomers, resulting in higher boiling points due to increased surface contact between molecules.
The boiling point of a mixture is significant in determining its composition and properties because different substances have different boiling points. By observing the boiling point of a mixture, one can infer the types of substances present in the mixture and their relative proportions. This information is crucial for understanding the behavior and characteristics of the mixture.
pure substances have a distinct boiling point. Adding more heat just makes the substance boil faster but the temperature stays the same. A mixture does not have a distinct boiling point. Adding more heat will make the temperature increase.
This because air is a mixture.

I will simple use the distillation method. That is I will separate the mixture of soluble from its solution when the solvent is to be recovered; heptane being more volatile (boiling point 98 degree) goes out first before heptanol (less volatile higher boiling point 176 degree)
1-heptanol: 175.8 °C 2-heptanol: 159 °C 3-heptanol: 156 °C

Heptane has 7 carbon atoms. So it has a greater surface area than methanol. Therefor heptane has a higher boiling point.In general, all else being equal the higher the molecular weight, the higher the boiling point. The molecular weight of methanol is 32, the molecular weight of heptane is 100. So, ignoring everything but that, you'd expect heptane to have a higher boiling point than methanol.A better question might be "why is the boiling point of methanol so much higher than that of ethane, which has a similar molecular weight (30)?" The answer to that is hydrogen bonding.

A specific mixture has a fixed boiling point.
pure substances have a distinct boiling point. Adding more heat just makes the substance boil faster but the temperature stays the same. A mixture does not have a distinct boiling point. Adding more heat will make the temperature increase.
The boiling point of a mixture is typically between the boiling points of its individual components due to the vapor pressure lowering effect of mixing. This can be estimated using methods like Raoult's law or boiling point elevation formula. The actual boiling point of the mixture would depend on the specific concentrations of the components in the mixture.
A mixture that consists of components with different boiling points will evaporate. As the mixture is heated, the component with the lower boiling point will vaporize first, leaving behind the component with the higher boiling point. This process is known as fractional distillation.

Distillation! Water and alcohol have different boiling points; one is lower than the other. Heat the mixture up until it one of the two boils away. In the case of alcohol and water, alcohol has the lower boiling point. Heat the mixture to just above the boiling point of alcohol but below the boiling point of water and voila!- you've separated the mixture.
