Hydrogen Bonding. The most powerful intermolecular force influencing neutral (uncharged) molecules is the hydrogen bond.If we compare the boiling points of methane (CH 4) -161ºC, ammonia (NH 3) -33ºC, water (H 2 O) 100ºC and hydrogen fluoride (HF) 19ºC, we see a greater variation for these similar sized molecules than expected from the data presented above for polar compounds. Boiling point 82.4 °C (760 torr) Vapour pressure at 20 °C 44 hPa MAK 400 ml/m3 (ppm) 980 mg/m3 2-Propanol is a colourless liquid under normal conditions of temperature and pressure. It is miscible with water in all proportions.

Which compound in each pair has the higher boiling point? acetone or 2-propanol. dimethyl ether or acetaldehyde

Heat of vaporization at boiling point = 330 kJ/kg; Specific heat capacity at 20 °C = 2.26 kJ/kg/K; Dynamic viscosity at 20 °C = 84 mPa s. Used as a plasticizer for 2-hydroxypropyl cellulose resins /1,1'-(propylenedioxy)di-2-propanol/ Kirk-Othmer Encyclopedia of Chemical Technology. 3rd ed., Volumes 1-26. New York, NY: John Wiley and Sons 2- propanol has greater boiling point, because hydrogen bonds between 2-propanol molecules, more energy is required to breake those bonds. Hydrogen bond is an electrostatic attraction between two polar groups that occurs when a hydrogen atom (H), covalently bound to a highly electronegative atom such as flourine (F), oxygen (O) and nitrogen (N The boiling point of 2-propanol is 82.3°C at standard pressure. 71 Explain, in terms of electronegativity differences, why a C O bond is more polar than a C H bond. [1] Answer==>There is a greater electronegativity difference in a C-O bond than in a C-H bond. 2-Propanol, sec-Propyl alcohol, IPA, Isopropanol, Isopropyl alcohol. Linear Formula: (CH 3) 2 CHOH.

The boiling point is a rough measure of the amount of energy necessary to separate a liquid molecule from its nearest neighbors. If the molecules interact through hydrogen bonding, a relatively large quantity of energy must be supplied to break those intermolecular attractions. Only then can the molecule escape from the liquid into the gaseous ksGM.
