Why does hexane have the highest boiling point?
Hexane has a larger surface area, and therefore the greater dispersion forces and higher boiling point.
Which is stronger pentane or hexane?
3. The n-hexane has the stronger attractions between its molecules. The n-pentane has the weaker attractions. The n-hexane has the larger molecules and the resulting stronger dispersion forces.
Why does pentane have a higher boiling point?
The n-pentane melts higher than isopentane because it can assume a rodlike shape in which adjacent molecules can pack closely together. The spherical neopentane molecules exert relatively little attraction on each other and so have a low boiling point.
Which has higher boiling point pentane?
The boiling point of n-pentane is \[{36.1^o}C\] and the boiling point of neopentane is \[{10^o}C\] . Hence n-pentane has higher boiling point than neopentane. Note: The surface area and the shape of molecules also has an impact on the melting point as well.
Does hexane have a high boiling point?
69 °C
Hexane/Boiling point
Does Vapour pressure increase with mass?
The bigger the molecule is and the more electrons it has, the bigger the London forces are. Bigger molecules usually have larger molecular weights; hence the correlation of vapor pressure with molecular weight.
Which has higher boiling point pentane or neopentane?
Answer: Neopentane, also called 2,2-dimethylpropane, is spherical-shaped. Pentane is rod-shaped and it does have stronger interactions and therefore a higher boiling point.
Which isomeric pentane has highest boiling point?
2,2-dimethyl pentane
Among isomeric pentanes , 2,2-dimethyl pentane has highest boiling point .

What kind of gas is alkane at room temperature?
At room temperature, the lighter alkanes are gases; the midweight alkanes are liquids; and the heavier alkanes are solids, or tars.
