Effect of Mass: If the molecule has more mass, it means that the number of electrons present is greater, and thus gives more strength to the dispersion forces that require more energy to break them, and these molecules will have higher melting and boiling points than others. I don't get how the intermolecular forces (Hydrogen bonding) relates to the heating curve of water. 1 Introduction 2. Max Karl Ernst Ludwig Planck, ForMemRS, (April 23, 1858 - October 4, 1947) was a German physicist who is regarded as the founder of thequantum theory, for which he received the Nobel Prize in Physics in 1918. very weak compared with kinetic energies of the molecules. Michael Faraday, (born September 22, 1791), Newington, Surrey, Eng. In chemistry, polarity is a separation of electric charge leading to a molecule or its chemical groups having an electric dipole moment, with a negatively charged end and a positively charged end.

Since O is more electronegative than C, the C-O bond is polar with the negative end pointing toward the O. (Btw, those are forces in molecules when, just by chance, one electron is on one end of a molecule and there are no electrons on a nearby end of a neighboring molecule--the transient negative charge of the electron pulls the transient positive charge of the non-electron. Intermolecular forces play a role in boiling points, for sure, but in this case it's a matter of molecular weight. There are intermolecular forces in methanejust as there were in bromine (also non-polar) in Section 2.
