Best Answer

NH3 is a polar molecule, so the molecules attract each other like magnets.
CH4 is completely symmetrical, so it is non polar.

Therefore, NH3 has a higher boiling point because it takes more energy to knock its molecules away.

What has a higher boiling point F2 or Br2?

Bromine has higher boiling point than Fluorine, in halogens family boiling point increases down the group due to molecular nature and increase in Vander waal's forces.


Which has a higher boiling point HI or HCl?

HI has a higher boiling point because of the dipole-dipole Intermolecular forces as well as the dispersion forces, which become more evident with molecular weight, which will dominate over the dipole-dipole forces, so HCl has a lower boiloing point.


Is the boiling point higher for compounds with a high viscosity?

Viscosity is the thickness of the compound. The thicker the compound the higher the intermolecular forces. The higher the intermolecular forces the higher the boiling point is.


How do you determine higher boiling points for compounds?

The intra and inter molecular forces will help to determine the higher boiling.Intra molecular forces are Polar/Non-polar covalent bonds and ionic bonds. Covalent bonds are stronger than ionic bonds.Polar covalent bonds will have a higher boiling point because non-polar covalent bonds are only affected by London forces.Intermolecular forces are hydrogen bonding, diapole-diapole and London. All molecules have London forces.Also the higher the electro-negativity the higher the boiling point.If all of the intra and inter molecular forces are the same, refer to the electro-negativity and size. The greater the electro-negativity and size, the higher the boiling point.


What inter molecular force would affect the boiling point the least?

Dispersion forces would have the least effect on the boiling point of a liquid. They are the weakest intermolecular forces.
