Why does 0.300 M KCl have a higher boiling point that 0.500 M glucose?
KCl is an ionic compound and glucose is a molecular compound. Ionic compounds have higher boiling points than molecular compounds.
Can you predict boiling point of a compound with the help of boiling points of elements in it?
The boiling point of a compound is influenced by various factors, including intermolecular forces and molecular weight, and cannot be accurately predicted solely based on the boiling points of elements in it. The presence of functional groups and molecular structure also play a significant role in determining the boiling point of a compound.
Which characteristic of the compound C5H12 causes it to have a higher normal boiling point than C2H6?
Predominantly its higher molecular mass. The higher mass of a molecule of C5H12 requires more energy to cause it to move fast enough to escape its intermolecular bonding than does the lower mass C2H6 molecule. The intermolecular bonding itself may be stronger in the higher molecular mass molecule, but this is relatively minor compared with the difference in molecular mass.
The boiling point of a molecular compound depends on the strength of?
the intermolecular forces between the molecules in the compound. Strong intermolecular forces, such as hydrogen bonding or dipole-dipole interactions, result in higher boiling points because more energy is required to overcome these forces and transition from a liquid to a gas state. Conversely, weaker intermolecular forces lead to lower boiling points as less energy is needed for the molecules to separate.
Why water has a higher boiling point than an organic molecule with same molecular weight?
Water has a higher boiling point than organic molecules of similar molecular weight due to hydrogen bonding between water molecules. Hydrogen bonds are stronger intermolecular forces compared to the van der Waals forces found in most organic molecules. These stronger hydrogen bonds require more energy to break, resulting in a higher boiling point for water.
How do ionic compounds and molecular compounds differ in their relative melting and bioling points?
Ionic compounds tend to have higher melting and boiling points compared to molecular compounds. This is because ionic bonds are generally stronger than the intermolecular forces present in molecular compounds, such as van der Waals forces. The strong electrostatic forces between ions in an ionic compound require more energy to overcome, leading to higher melting and boiling points.
Calcium floride is an ionic compound Benzine is a molecular compound Which one would you expect has a higher boiling point?
Ionic compounds, generally, have higher boiling point because they are electrostatically attracted to each other. On the other hand, molecular compounds only have weak Van Der Waal's forces, or otherwise known as intermolecular forces, to bond them. Therefore, relatively, it takes more heat energy to break the bonds of the ionic compound to change it's state than to break the intermolecular forces.
Why does heptane have a higher boiling point than methanol?
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.
Is propanoic anhydride or butanoic anhydride having a higher boiling point?
All else being equal/similar, the higer the molecular weight, the higher the boiling point.
Is the boiling point higher for compounds with a high viscosity?
Not necessarily. Viscosity and boiling point are two separate properties of a compound. Viscosity is a measure of a liquid's resistance to flow, while boiling point is the temperature at which a substance changes from a liquid to a gas. While there may be some correlation between viscosity and boiling point for certain compounds, it is not a direct relationship.
What factors contribute to a substance having a higher boiling point compared to others?
The main factors that contribute to a substance having a higher boiling point compared to others are its molecular weight, intermolecular forces, and polarity. Substances with higher molecular weight and stronger intermolecular forces, such as hydrogen bonding, tend to have higher boiling points. Additionally, substances that are more polar also tend to have higher boiling points due to stronger attractions between molecules.
Could someone describe properties that would help you to distinguish an ionic compound from a molecular compound?
Ionic compounds typically have higher melting and boiling points compared to molecular compounds, as they have strong electrostatic forces between oppositely charged ions. Ionic compounds also tend to be soluble in water and conduct electricity when dissolved, due to the presence of free ions. In contrast, molecular compounds have lower melting and boiling points, are often insoluble in water, and do not conduct electricity in their pure state.
