Highest boiling point between organic compounds

In summary, the substances with approximately the same relative molecular mass are being compared for their boiling points. The substance with OH, E, is likely to have the highest boiling point due to hydrogen bonding. It is recommended to confirm this answer by looking up the boiling points of the compounds.

Yes, I realized that after I posted. Will make sure to do that first next time. Thanks!
 

Related to Highest boiling point between organic compounds

1. What is the definition of boiling point?

The boiling point of a substance is the temperature at which the vapor pressure of the liquid is equal to the atmospheric pressure, causing the liquid to change state from a liquid to a gas.

2. Why is the boiling point important for organic compounds?

The boiling point of organic compounds can provide information about their physical properties, such as their volatility and intermolecular forces. It can also affect their applications and uses, such as in distillation and purification processes.

3. How does molecular weight affect the boiling point of organic compounds?

In general, as the molecular weight of an organic compound increases, its boiling point also increases. This is because larger molecules have stronger intermolecular forces, making it harder for them to escape into the gas phase.

4. What factors can influence the boiling point of organic compounds?

The boiling point of organic compounds can be affected by factors such as molecular weight, branching, functional groups, and external pressure. These factors can alter the strength of intermolecular forces, which in turn can affect the boiling point.

5. How can the boiling point be used to identify organic compounds?

The boiling point can be used as a physical property to help identify unknown organic compounds. By comparing the boiling point of a substance to known values, it can provide clues about its molecular structure and potential functional groups present.
