What type of intermolecular force is Br2?
What type of intermolecular force is Br2?
London dispersion
Is Br2 dipole-dipole?
London Forces exist in all molecules. bromine Br2 114 −7 liquid iodine I2 133 114 solid The intermolecular forces (dipole-dipole, hydrogen bonding and London) are all a form of dipole- dipole, whether temporary or permanent.
Does Br2 have London dispersion forces?
London forces (also called dispersion or induced-dipole forces) exist in all molecular samples – both polar and nonpolar compounds. Figure 1: London forces for two Br2 molecules. (a) Represents the two molecules before the induced dipoles appear; (b) shows the alignment of the induced dipoles.
Does bromine have London dispersion forces?
Bromine is a liquid at room temperature, while chlorine and fluorine are gases, whose molecules are much further apart from one another….London Dispersion Forces.

Which is stronger intermolecular hydrogen bonding or intramolecular hydrogen bonding?
Intramolecular forces are stronger because for covalent bonds they involve the actual sharing of electrons because the molecule forming intramolecular hydrogen bonding contains two groups such that one group contains hydrogen atom links to the highly electronegative atom and the other group should contain a highly …
Why are dipole dipole forces typically stronger than London dispersion forces?
Dipole-dipole forces occur when the molecules are polar, and the positive side of one molecule is slightly attracted to the negative side of another. Because London dispersion forces are temporary, they’re weaker than the permanent dipole-dipole attractions.
What is extensive hydrogen bonding?
Mainly through electrostatic attraction, the donor atom effectively shares its hydrogen with the acceptor atom, forming a bond. Because of its extensive hydrogen bonding, water (H2O) is liquid over a far greater range of temperatures that would be expected for a molecule of its size.
How is the strength of hydrogen bonds determined?
Order of hydrogen bond strength: O−H⋅⋅⋅N > O−H⋅⋅⋅O > N−H⋅⋅⋅N > N−H⋅⋅⋅O.
Why are hydrogen bonds stronger than London dispersion forces?
Why are hydrogen bonds stronger than dipole-dipole forces which are stronger than dispersion forces? Dipole is permanent, so the attraction is stronger. With hydrogen bonds you can only see attraction between molecules that are polar. This attraction increases with the increasing total number of electrons.
