Why C12H26 has a higher boiling point?

The more intermolecular mass is added, the higher the boiling point. Intermolecular forces of alkenes gets stronger with increase in the size of the molecules. Hence, C 12 H 26 C_{12}H_{26} C12H26 has a higher boiling point than C 8 H 18 C_8H_{18} C8H18 .

How do you know which compound has the highest boiling point?

Compounds with stronger intermolecular forces, larger masses, and less branching will have higher boiling points. Compounds II and III only exhibit intermolecular London dispersion forces, so they would be the two lowest boiling compounds (weakest intermolecular forces).

Does C3H8 have a high boiling point?

-43.6°F (-42°C)
Propane/Boiling point

Which compound has the highest boiling point *?

Propan-1-ol
Propan-1-ol has the highest boiling point because propan-1-ol contains H-bonding in their structure. Hence, Propan – 1 – ol has the highest boiling point amongst the given options. So, the correct answer is option A. Note- The normal boiling point of a compound is an indicator of the volatility of that compound.

Why C12H26 has higher boiling point than C8H18?

This is a consequence of the increased kinetic energy needed to break the intermolecular bonds so that individual molecules may escape the liquid as gases. C16H34 is larger than C12H26 , C8H18 and C3H8 and the larger a molecule is, the more intermolecular forces there are between those molecules.

Which hydrocarbons has the highest boiling point?

The normal alkane has the highest boiling point. The physical properties of a series of cycloalkanes of increasing molecular weight are similar to those of a series of alkanes. The densities increase, as do the boiling points (Table 3.3).

Which compounds have higher boiling points?

Large molecules have more electrons and nuclei that create van der Waals attractive forces, so their compounds usually have higher boiling points than similar compounds made up of smaller molecules.

What is the highest boiling point?

Tungsten
The chemical element with the lowest boiling point is Helium and the element with the highest boiling point is Tungsten.

Which has a higher boiling point CH4 or C3H8?

3. Of the molecules that are left, the largest one (C3H8) likely has the strongest London dispersion forces. The smallest (CH4) likely has the weakest intermolecular forces. Higher boiling points will correspond to stronger intermolecular forces.

Why does C12H26 has a higher boiling point than C8H18?

Which compound will have the highest boiling point quizlet?

The compound with the highest intermolecular forces will have the highest boiling point. Only choice C is capable of hydrogen bonding (having an O-H bond) and has the highest overall intermolecular forces and therefore the highest boiling pt.
