Why does water have stronger intermolecular forces than carbon dioxide yet carbon dioxide has more mass?
Water has stronger intermolecular forces than carbon dioxide due to the presence of hydrogen bonds in water, which arise from its polar nature and the highly electronegative oxygen atom. In contrast, carbon dioxide is a nonpolar molecule with weaker London dispersion forces dominating its interactions. Although carbon dioxide has a greater molar mass, the strength of intermolecular forces is influenced more by molecular structure and polarity than by mass alone. Thus, the strong hydrogen bonding in water leads to higher intermolecular attractions compared to the weaker forces in carbon dioxide.
What else can I help you with?
What is the stronger intermolecular force between CO2 and COS?
The stronger intermolecular force between CO2 (carbon dioxide) and COS (carbonyl sulfide) is found in COS. While CO2 is a nonpolar molecule and primarily exhibits London dispersion forces, COS is polar and can engage in dipole-dipole interactions in addition to dispersion forces. The presence of a polar bond in COS contributes to stronger intermolecular attractions compared to the nonpolar CO2.
Why selenium dioxide is solid at room temperature while sulfur dioxide is a gas?
Selenium dioxide has stronger intermolecular forces than sulfur dioxide due to its larger atomic size, making it a solid at room temperature. Sulfur dioxide is a gas because it has weaker intermolecular forces due to its smaller atomic size.
Are carbon monoxide have no intermolecular forces?
Carbon monoxide does have intermolecular forces. The molecule is polar due to the difference in electronegativity between carbon and oxygen, leading to dipole-dipole interactions. These intermolecular forces contribute to properties such as boiling and melting points.
How do hydrogen bounds compare with other intermolecular forces?
Hydrogen bonds are much stronger than other intermolecular forces.
How does carbon chain affect the melting point?
Generally, as the carbon chain length increases, the melting point of a compound also tends to increase. This is because longer carbon chains result in stronger intermolecular forces, such as London dispersion forces, leading to a higher melting point. Shorter carbon chains have weaker intermolecular forces, so they typically have lower melting points.
Which has the higher melting point sulfur dioxide or carbon dioxide?
Sulfur dioxide has a higher melting point than carbon dioxide. This is because sulfur dioxide is a smaller molecule with stronger intermolecular forces, making it more difficult to break the bonds in order to melt the substance.

What pure compound has the highest total intermolecular forces per molecule at 25 degree Celsius carbon dioxide water rubbing alcohol table sugar or gasoline?
Water has the highest total intermolecular forces per molecule at 25°C compared to carbon dioxide, rubbing alcohol, table sugar, and gasoline. Water molecules can form hydrogen bonds with each other, leading to stronger intermolecular forces compared to the other compounds listed.
Why selenium dioxide is solid at room temperature while sulfur dioxide is a gas?
Selenium dioxide has stronger intermolecular forces than sulfur dioxide due to its larger atomic size, making it a solid at room temperature. Sulfur dioxide is a gas because it has weaker intermolecular forces due to its smaller atomic size.
Can carbon dioxide attract carbon dioxide?
Yes, carbon dioxide molecules can be attracted to each other through intermolecular forces like van der Waals forces. These weak forces help hold the molecules together when they are in close proximity.
Explain how could attractions between molecules could cause water to have a higher boiling point than carbon dioxide?
Attractions between water molecules, such as hydrogen bonding, are stronger than the dispersion forces between carbon dioxide molecules. This results in water requiring more energy to break these intermolecular attractions and reach its boiling point than carbon dioxide.
Why does sulfur dioxide have low boiling point?
Sulfur dioxide has a low boiling point because it is a small molecule with weak intermolecular forces. The forces holding sulfur dioxide molecules together are relatively weak, requiring less energy to break and therefore resulting in a lower boiling point compared to compounds with stronger intermolecular forces.
Why does H2O have a higher point than CO2?
H2O (water) has a higher melting point and boiling point than CO2 because of the hydrogen bonds that exist between the water molecules. The hydrogen bonds are strong intermolecular forces (though they are classified as a weak bond), and help to hold separate water molecules together. Thus, the boiling point of water is higher than carbon dioxide, though they are similar in composition and mass.
Are carbon monoxide have no intermolecular forces?
Carbon monoxide does have intermolecular forces. The molecule is polar due to the difference in electronegativity between carbon and oxygen, leading to dipole-dipole interactions. These intermolecular forces contribute to properties such as boiling and melting points.
How do hydrogen bounds compare with other intermolecular forces?
Hydrogen bonds are much stronger than other intermolecular forces.
What can you say about the relative strength of the intermolecular forces in the two compounds?
The relative strength of intermolecular forces depends on the types of molecules involved. Compounds with hydrogen bonding, such as water, tend to have stronger intermolecular forces compared to those with only London dispersion forces, like diethyl ether. This results in higher boiling points for compounds with stronger intermolecular forces.
How does carbon chain affect the melting point?
Generally, as the carbon chain length increases, the melting point of a compound also tends to increase. This is because longer carbon chains result in stronger intermolecular forces, such as London dispersion forces, leading to a higher melting point. Shorter carbon chains have weaker intermolecular forces, so they typically have lower melting points.
