This is down to 2 factors; firstly, the only bond is C-H, which is non-polar due to carbon and hydrogen having very similar electronegativities, secondly hexane is symetric so any polarity in the molecule 2-Pentanol | C5H12O | CID 22386 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety/hazards/toxicity information, supplier lists, and more. C) linear trigonal planar The hydroxyl group of 1-pentanol is more exposed than it is in 3-pentanol (which is flanked by two bulky alkyl groups), so it will be better able to hydrogen bond with its fellows. Intermolecular forces exist between molecules and influence the physical properties. Due to the presence of polar protic -OH group and a polar C-O bond, 1-pentanol is a molecular polar compound. The key . So let's try this. Wiki User. The greater the polarity the higher the boiling point. The following pairs of molecules experienced pen tunnel with another molecule of fentaNYL. The reason for this is the shape of 2-Pentanol is less ideal for the intermolecular forces, in this case hydrogen bonds, of the molecule thus causing for the intermolecular forces to be slightly weakened which causes a decrease in the boiling point of 2-Pentanol. followed by acidification yields 2,3-dimethyl-2-pentanol.
