Could someone explain the differences in changes of state in terms of intermolecular forces of attraction between a short molecule i.e. methane and a longer molecule i.e. pentane.?

In the absence of any other functional groups, the longer the alkane (pentane is longer than methane), the greater will be the intermolcular forces. Thus, it will take more energy to change states for the longer molecule than the shorter (b.p. will be higher, etc.). This arises from the fact that the more carbon atoms (or the more atoms, in general), the greater will be the dispersion forces. These may very well be the only intermolecular forces present, if there are no dipoles, or hydrogen bonding.

Attraction between molecules of the same substance is called what?
It is intermolecular force of attraction, it may be 1- dipole - dipole interaction, 2- vander waal's force of attraction.
What is the term for the attraction between atoms in a molecule?
Connection
Van Der Waals Forces Are Attractive Forces Between Molecules?
Van der waals forces (ie induced dipole-dipole interactions) is a weak intermolecular attraction that exist but one molecule and another whether polar or non-polar.
What is a attraction between molecules of different substances?
Adhesive forces are the attraction between molecules of different substances. This differs from cohesive forces which is attraction between same substances.
Which kind of forces is a dipole-dipole force?
the permanent dipole of one molecule attracts the permanent dipole in a different polar molecules.
Which kind of force is a dipole- dipole force?
Intermolecular attraction
What is the intermolecular forces of CH3F?
These are polar forces, intermolecular forces of attraction between molecules.
The intermolecular force between molecules of oxygen is dipole dipole in nature?
Oxygen is a non polar molecule so its molecules have only Vander waal's forces of attraction.
What is the difference between an intermolecular and an intramolecular bond?
intERmolecular means between molecules IntRAmolecular means within A molecule.
What is the differcence between cohesion and adhesion?
adhesion is the intermolecular attraction between 'unlike-molecules' usually refered to the attraction or joining of two different objects of fluids to each other cohesion is the intermolecular attraction between 'like-molecules' usually refered to the strngth with which the particles of an object of fluid attract to each other
The difference between cohesion and adhesion?
Adhesion is the intermolecular attraction between 'unlike-molecules' (usually referred to the attraction or joining of two different objects of fluids to each other).Cohesion is the intermolecular attraction between 'like-molecules' (usually referred to the strength with which the particles of an object of fluid attract to each other)
Difference between adhesion and cohesion?
Adhesion is the intermolecular attraction between 'unlike-molecules' (usually referred to the attraction or joining of two different objects of fluids to each other).Cohesion is the intermolecular attraction between 'like-molecules' (usually referred to the strength with which the particles of an object of fluid attract to each other)
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 ..
Is the attraction between sodium chloride and water a intermolecular force of an intramolecular bond?
its basically the hydrogen bonding mainly responsible for this attraction.
How do cohesion and adhesion differ?
Cohesion and adhesion differ because cohesion is an attraction between molecules of the same substance. Adhesion is an attraction between molecules of different substances.Adhesion is the intermolecular attraction between 'unlike-molecules' (usually referred to the attraction or joining of two different objects of fluids to each other).Cohesion is the intermolecular attraction between 'like-molecules' (usually referred to the strength with which the particles of an object of fluid attract to each other).== == == ==
The attractive force between masses is known as?
cohesion: the intermolecular attraction between like molecules
Attraction between molecules of the same substance is called what?
It is intermolecular force of attraction, it may be 1- dipole - dipole interaction, 2- vander waal's force of attraction.
