states of matter and the kinetic molecular theory
(1 answer)

although molecuels behave independently int he gas state, their behavior in the liquid an solid sates is more complicated

dipole dipole
(1 answer)

dipole induced dipole

the larger the elctron cloud, the more easily polarized it is
(1 answer)

the easier it is to induce a dipole

dipole induced dipole
(1 answer)

induced dipole induced dipole

what holds nonpolar moelcules together
(1 answer)

all molecules are held together yb dispersion forces

all molecules are held together yb dispersion forces
(1 answer)

even the attraction between polar molecuels invovles mroe dispersion force than dipole dipole attraction

bromine is a liquid
(1 answer)

chlorine is a gas

the positive end fo one molecule attracts teh negative end of anotehr molecule an vice versa
(1 answer)

this attraction si called dipole-dipole attraction

without such attraction all substances would be gases
(1 answer)

in both liquids and solids, molecules are held together to a finite volume by their attraction for one another

although molecuels behave independently int he gas state, their behavior in the liquid an solid sates is more complicated
(1 answer)

molecules do attract one another

intermolecular forces are the electrostatic forces of attraction between moelcules or between ions and molecules
(1 answer)

there are a variety of different types

hydrogen bonding
(1 answer)

dipole dipole

Intermolecular Forces, Liquids, and Solids
(3 answers)

states of matter and the kinetic molecular theory
intermolecular forces
summary of intermolecular forces

there are a variety of different types
(1 answer)

there is the attraction between ions and polar moleues

but in these halogens there are no polar molecuels to induce the dipole so how does the induced dipole attraction work
(1 answer)

as the termpeatue is decreased, moelcuels slow down

summary of intermolecular forces
(1 answer)

in gneral, for molecsize, the strength of intermoleculr forces decrease int he order

so nonpolar ioine is a solid
(1 answer)

bromine is a liquid

chlorine is a gas
(1 answer)

but in these halogens there are no polar molecuels to induce the dipole so how does the induced dipole attraction work

intermolecular forces
(6 answers)

intermolecular forces are the electrostatic forces of attraction between moelcules or between ions and molecules
intermolecular force are considerably weaker than intramoelcualr bonds
when two molecuesl ahv dipole moments, they attract one another
intermolecular force influence solubility
some molecuels are nonpolar and yet at ssufficiently low temperatuers they will liquefy and solidify
the larger the elctron cloud, the more easily polarized it is

as the water moelcule approaches an oxygen molecule, thhe dipole of the awter molecule distorts the electron distribution int he oxygen molecule
(1 answer)

the result is an attraction between teh dipole of the water molecule and the induced dipole of the oxygen molecule

this lads to a mutual disotrtion of the electorn clouds on adjacent molecuels
(1 answer)

a temporary induced dipole attraction is the result

thse induced dipoles are temporary displacements int he electron cloud surroundign the atoms ina a molecule
(1 answer)

the inducement of such temproary dipoles explians how a nonpolar molecule liek oxygen can dissolve in polar solvent liek water

even the attraction between polar molecuels invovles mroe dispersion force than dipole dipole attraction
(1 answer)

a dispersion force is the attraction between induced dipoles

there is the attraction between ions and polar moleues
(1 answer)

between polar moelcuels themselves

the molecules appraoch one anotehr long enought o allow the electron could and nuclei of different molecuels to interact
(1 answer)

this lads to a mutual disotrtion of the electorn clouds on adjacent molecuels

in both liquids and solids, molecules are held together to a finite volume by their attraction for one another
(1 answer)

the volume is approximately the same for the qliujid and solid sates, mcuh smaller than for the gas states

in gneral, for molecsize, the strength of intermoleculr forces decrease int he order
(1 answer)

hydrogen bonding

the greater the forces of attraction between molecules,t eh greater the energy required to separate them
(1 answer)

polar compounds therefore have a hgiher boiling point, melting point, heat of vaporization,a nd viscosity than nonpolar molecules of comparable size

the inducement of such temproary dipoles explians how a nonpolar molecule liek oxygen can dissolve in polar solvent liek water
(1 answer)

as the water moelcule approaches an oxygen molecule, thhe dipole of the awter molecule distorts the electron distribution int he oxygen molecule

and between nonpolar molecules
(1 answer)

those forces not invoving ions aer gnerally referred to as van der Waals forces

a dispersion force is the attraction between induced dipoles
(1 answer)

thse induced dipoles are temporary displacements int he electron cloud surroundign the atoms ina a molecule

as the termpeatue is decreased, moelcuels slow down
(1 answer)

the molecules appraoch one anotehr long enought o allow the electron could and nuclei of different molecuels to interact

intermolecular force influence solubility
(1 answer)

polar molecuels tend to dissolve in polar solvents

this attraction si called dipole-dipole attraction
(1 answer)

the greater the forces of attraction between molecules,t eh greater the energy required to separate them

some molecuels are nonpolar and yet at ssufficiently low temperatuers they will liquefy and solidify
(1 answer)

what holds nonpolar moelcules together

polar molecuels tend to dissolve in polar solvents
(1 answer)

non polar molecuels tend to dissolve innonpolar solvents

the easier it is to induce a dipole
(1 answer)

so nonpolar ioine is a solid

between polar moelcuels themselves
(1 answer)

and between nonpolar molecules
