WebAboutTranscript. Dipole–dipole forces occur between molecules with permanent dipoles (i.e., polar molecules). For molecules of similar size and mass, the strength of these forces increases with increasing polarity. Polar molecules can also induce dipoles in nonpolar molecules, resulting in dipole–induced dipole forces.

http://chemistry.elmhurst.edu/vchembook/213organicfcgp.html WebMay 8, 2014 · Polarity has a huge affect on how attracted a chemical is to other substances. Some molecules have a positively charged side and a negatively charged side. For example, the positive side is attracted to the negative side of another molecule (opposites attract). The larger the charge difference, the more polar a molecule is.

WebIn your case, hydrogen is always the same since we're always talking about alcohols. Alkyl substituents donate electron density to the oxygen atom, so it is less eager to draw electron denstity from the hydrogen bond and will make it less polar. Change the alkyl for a primary alkyl chloride for example and the effect will be reversed.
