Sucrose can form several Hydrogen Bonds with Water. This is because it has many -OH groups. The O is electronegative enough to pull H's single electron away from its nucleus to such an extent that its single proton is partially exposed. This proton can then form hydrogen bonds with other O's (such as those in water). This works vice versa with Water because Water also has -OH groups. This is an intermolecular force, which is also referred to as intermolecular bonds.
Another, is instantaneous dipole - induced dipole forces (bonds) and the third is permanent - permanent dipole forces (bonds). The first occurs between all substances, and the latter is because both water and sucrose are polar molecules.
Thanks,
TC.

What is the suitable hypothesis to investigate evaporation and determine the relationship between evaporation and inter molecular forces?
Evaporation occur when intermolecular forces weakened.
How do London forces and dipole-dipole forces between molecules differ from force between ions crystals?
The forces between ions in crystals are ionic bonds. These bonds are stronger and are a much more extreme version of electron sharing between metal atoms and nonmetal atoms. London forces and dipole-dipole forces are attractive forces that occur between covalently bonded nonmetal atoms.
Which bonds are held together by intermolecular forces?
These are usually called "van der Waals" bonds. Some of the strongest of these types of bonds occur between hydrogen atoms attached by chemical bonds to a particular other atom in the same molecule but also attracted by electron-rich areas on other molecules in their vicinity, and these are often called "hydrogen bonds."
London dispersion forces occur between molecules that are?
nonpolar
The three types of bonds in an atom?
The three you may be looking for are covalent bonds, Ionic bonds and intermolecular forces. Covalent bonds are between atoms and they share electrons. An example is O2 where 4 electrons are shared between the two atoms. Ionic bonds occur between atoms and one atom takes the electrons from the other such as NaCl. Cl takes one electron from Na so both follow the octet rule. Intermolecular forces include dispersion forces, hydrogen bonding and dipole dipole interactions. In intermolecular forces the electrons in an atom are dispereded within the electron cloud in a way that a positive and negative region can occur in an atom at anyone time and anywhere. A popular example is hydrogen bonding in water. Water is H2O. The O is more electronegative which will keeps electron close to it even from hydrogen. This allows the O atom to bee negative and the H atoms to be positive. Opposites attract and the positive end of one molecule attracts to the negative O of another molecule.
What is the relationship between the strength of the intermolecular forces and boiling point?
Boiling can only occur when the kinetic energy of heat overcomes the intermolecular forces holding a liquid together, so the greater the intermolecular forces, the higher the boiling point.
Is the bonds that cause gaseous Cl2 to become liquid when cool intramolecular or intermolecular?
Intermolecular because intermolecular forces occur between molecules, not within the same molecule. Specifically the forces are London dispersion forces, due to the interaction of instantaneous dipoles.
What is the suitable hypothesis to investigate evaporation and determine the relationship between evaporation and inter molecular forces?
Evaporation occur when intermolecular forces weakened.
What type of intermolecular forces occur in highly volatile liquids?
London Dispersion
What type of intermolecular forces does methane CH4 have?
In a single molecule of CH4 you would have intramolecular forces that are covalent bonds. The intermolecular forces that exist between molecules of CH4 are called dispersion forces. These forces are the only intermolecular forces that occur between non-polar molecules.
How did you determine the intermolecular force for these compounds?
Intermolecular forces (forces between molecules) can be of several types. There are hydrogen bonds, dipole-dipole interactions, induced dipole interactions, and dispersion forces. Hydrogen bonds occur when a hydrogen is bonded to either an oxygen, nitrogen or sulfur atom. Dipole-dipoles occur when the molecule is polar and has a dipole moment, and induced dipoles occur as transient dipoles when one molecule approaches another and induces electron movement. Dispersion forces occur in all molecules, even non polar ones.
What changes occur at the molecule level when butter melts in a hot pan?
The intermolecular forces are weakened.
Do inter-molecular forces occur as a result of being in the liquid state or does a liquid state exist because of inter-molecular forces?
The liquid state is caused by intermolecular forces.
Bases of DNA are linked together by intermolecular forces are called?
The two strands of DNA are linked together by hydrogen bonds which occur between the nitrogen bases opposite one another along the molecule.
How do London forces and dipole-dipole forces between molecules differ from force between ions crystals?
The forces between ions in crystals are ionic bonds. These bonds are stronger and are a much more extreme version of electron sharing between metal atoms and nonmetal atoms. London forces and dipole-dipole forces are attractive forces that occur between covalently bonded nonmetal atoms.
What are inter and intra molecular bond?
Intra-molecular bonding ocuurs between atoms of the single large molecule ,where the inter-molecular bonding occurs between molecules ..
What type of interaction exists in a non-polar species?
Non-polar species will interact through dispersion forces. Dispersion forces are attraction between the positive nucleus of an atom and the negative electrons of another atom. Dispersion force, also known as London forces, are the weakest intermolecular force and occur from temporary dipoles forming in molecules.
