What else can I help you with?
Glycerol boils at a slightly higher temperature than does water. this reveals that glycerols attractive forces are?
Glycerol's higher boiling point compared to water indicates that glycerol molecules have stronger intermolecular forces, such as hydrogen bonding or dipole-dipole interactions. These stronger attractive forces require more energy to overcome, resulting in a higher boiling point for glycerol.
Why is glycerol solid at room temperature?
Glycerol is a solid at room temperature because it has a high melting point of around 18°C. The intermolecular forces between glycerol molecules are relatively strong, which allows them to pack closely together in a solid form.
Do you expect the viscosity of glycerol to be larger or smaller than that of 1-propanol?
Glycerol is expected to have a larger viscosity than 1-propanol because glycerol is a larger molecule with more hydrogen bonding sites, leading to stronger intermolecular forces. These stronger interactions result in greater resistance to flow and higher viscosity compared to 1-propanol.
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.
What intermolecular forces are present in cl2?
London forces are present in chlorine molecules.
Which liquid has a higher surface tension glycerol or hexane?
Glycerol has a higher surface tension compared to hexane. This is because glycerol is more polar than hexane, leading to stronger intermolecular forces between glycerol molecules which results in a higher surface tension.

Why is glycerol so viscous?
Glycerol is viscous because it has a high molecular weight and a large number of hydroxyl groups, which contribute to strong intermolecular forces and hydrogen bonding. These interactions lead to cohesive forces between glycerol molecules, resulting in a thicker, more viscous liquid.
Why is glycerol solid at room temperature?
Glycerol is a solid at room temperature because it has a high melting point of around 18°C. The intermolecular forces between glycerol molecules are relatively strong, which allows them to pack closely together in a solid form.
Why is boiling point of glycerol high than hexane?
in glycerol, every molecules are associated together with strong Hydrogen bond which is due to the OH functional group, this H-bond is absent in hexane.Hence it is so, which means more energy is required to break the bond b/w each molecule to release it as vapours
What isC3H8O3's most important intermolecular force?
The most important intermolecular force in C3H8O3 (glycerol) is hydrogen bonding. This is because glycerol contains hydroxyl groups that can form hydrogen bonds with neighboring molecules, leading to stronger intermolecular interactions.
Why vapour pressure of glycerol is lower than isopentane?
The vapor pressure of a substance is related to its intermolecular forces. Glycerol has strong hydrogen bonding between its molecules, which causes them to stick together more tightly compared to the weaker van der Waals forces in isopentane. This makes it harder for glycerol molecules to escape into the gas phase, resulting in a lower vapor pressure compared to isopentane.
What interaction is not a type of intermolecular force?
Intramolecular forces are not intermolecular forces !
Do you expect the viscosity of glycerol to be larger or smaller than that of 1-propanol?
Glycerol is expected to have a larger viscosity than 1-propanol because glycerol is a larger molecule with more hydrogen bonding sites, leading to stronger intermolecular forces. These stronger interactions result in greater resistance to flow and higher viscosity compared to 1-propanol.
What is the intermolecular ammonia and ammonia?
The intermolecular forces are hydrogen bonding.
How do thermal and intermolecular forces behave with each other?
When there is more thermal energy, then there are less 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.
