which imf has the lowest boiling point?
13794
Compounds II and III only exhibit intermolecular London dispersion forces, so they would be the two lowest boiling compounds (weakest intermolecular forces). Because compound III has more branching, these London dispersion forces would be weaker, resulting in a lower boiling point than compound II.

When simple molecular substances melt or boil, it is these weak intermolecular forces that are overcome. The covalent bonds are not broken. ... In general, the bigger the molecule, the stronger the intermolecular forces, so the higher the melting and boiling points.

As atmospheric pressure decreases, water boils at lower temperatures. At sea level, water boils at 212 °F. With each 500-feet increase in elevation, the boiling point of water is lowered by just under 1 °F.

It has an initial boiling point (IBP) of about 35 °C and a final boiling point (FBP) of about 200 °C, and it contains paraffins, naphthenes (cyclic paraffins) and aromatic hydrocarbons ranging from those containing 4 carbon atoms to those containing about 10 or 11 carbon atoms.

Boiling points are a measure of intermolecular forces. The intermolecular forces increase with increasing polarization of bonds. Boiling point increases with molecular weight, and with surface area.

Hi Maria, For pure water, the boiling point is 100 degrees Celsius (212 Fahrenheit) at one atmosphere of pressure, and the melting point is 0 degrees Celsius (32 degrees Fahrenheit) at one atmosphere of pressure. ... For saltwater, the boiling point is raised, and the melting point is lowered.

The stronger an intermolecular force, the higher the boiling point of the substance will be , because stronger intermolecular bonds require more energy to break and this energy is supplied in the form of heat when boiling, substances with stronger bonds will have a higher boiling point.

The core principle is that the stronger the IMFs in the sample of molecules, the more strongly they interact, which means they stick together more. That leads to the following trends: Stronger IMF → Higher melting and boiling points (harder to melt and boil) Stronger IMF → Lower vapor pressure (harder to boil)

Boiling points Methanal is a gas (boiling point -21°C), and ethanal has a boiling point of +21°C. That means that ethanal boils at close to room temperature. The other aldehydes and the ketones are liquids, with boiling points rising as the molecules get bigger.

The halogens have low melting points and low boiling points. This is a typical property of non-metals. Fluorine has the lowest melting and boiling points. The melting and boiling points then increase as you go down the group.

Intermolecular forces (IMF) are the forces which mediate interaction between molecules, including forces of attraction or repulsion which act between molecules and other types of neighboring particles, e.g. atoms or ions.

The boiling point is the temperature at which the vapor pressure of a liquid is equal to the external pressure. As the altitude increases, the boiling point decreases.
