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.

What is methanol melting and boiling point?
Methenol does not exist, at least not in chemistry;However , if it is a misspelling of methanol (CH3OH, spelled with 'a') the boiling point is 65 °C, 338 K, 149 °F
Where can you find the methanol boiling point curve at several pressures?
You can find the methanol boiling point curve at various pressures in chemical engineering handbooks, thermodynamic databases, or online resources such as NIST Chemistry WebBook. These sources provide detailed information on the boiling points of methanol at different pressures.
Is the melting point for methanol higher than silicon?
Since at normal room temperature methanol is a liquid and silicon is a solid, it should be fairly obvious that the answer is "no."
Does chlorine have a higher boiling point than iodine?
Yes, chlorine has a higher boiling point than iodine. Chlorine has a boiling point of -34.6 degrees Celsius, while iodine has a boiling point of 184 degrees Celsius.
Why does heptane have a higher boiling point than pentane?
The carbon skeleton of pentane contains 5 carbon atoms, the carbon skeleton of heptane contains 7 carbon atoms. The main reason for increased boiling point are London dispersion forces, these increase the with the number of electrons- so as heptane has more electrons its dispersion forces are greater and the boiling point is higher. Another contributory factor is the mass as the molecule of heptane is heavier and this means it takes more energy to get it to vaporise.
How is a mixture o heptane boiling point 98C and heptanol boiling point 176C?
The boiling point of a mixture of heptane and heptanol will be between the boiling points of the individual components due to their different boiling points. The exact boiling point of the mixture will depend on the relative proportions of heptane and heptanol in the mixture. It will likely be lower than the boiling point of heptanol and higher than the boiling point of heptane.
What C7H16 isomer has the highest boiling point?
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.
Which type of bonding explains why methanol has a much higher boiling point that methane?
Methanol has a much higher boiling point than methane due to hydrogen bonding. In methanol, the presence of an -OH (hydroxyl) group allows for strong intermolecular hydrogen bonds between methanol molecules, whereas methane only exhibits weaker van der Waals forces. These hydrogen bonds require more energy to break, resulting in a higher boiling point for methanol compared to methane.
Why methane mercaptan has a lower boiling point than methanol even though methyl mercaptan has a higher molecular weight?
For the same reason that water isn't a gas. Oxygen is highly electronegative and the hydrogen bonding present in water and methanol raises the intermolecular attractive forces and results in a higher boiling point.
Why does the boiling point of methylated spirits drop?
The boiling point of methanol is lower than the boiling point of ethanol.
How would you separate a mixture of heptane and heptanol at boiling point?
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.
What is methanol melting and boiling point?
Methenol does not exist, at least not in chemistry;However , if it is a misspelling of methanol (CH3OH, spelled with 'a') the boiling point is 65 °C, 338 K, 149 °F
Why does CH3OH have a higher boiling point than CH3NH2?
Since oxygen has a higher electronegativity than nitrogen, the hydroxyl radical is more polar than the amide radical, and hence, creates a stronger electrostatic attraction between molecules and consequently a higher boiling point.
What is condensation point for methanol?
Condensation point is the same as boiling point of methanol: 65 °C, 338 K, 149 °F
What is the boling point of methyl alcohol?
The boiling point of methyl alcohol (methanol) is 64.7oC.
What molecule has the highest boiling point methane chloromethane or methanol?
Methanol has the highest boiling point among methane, chloromethane, and methanol. This is because methanol has stronger intermolecular forces (hydrogen bonding) compared to methane (only dispersion forces) and chloromethane (dipole-dipole forces).
What is the octane rating of methanol?
The octane rating of methanol depends on the octane rating scale measurement type used, n-Heptane is the zero point of the octane rating scale then the octane rating of methanol is 115
