WebApr 10, 2024 · It shows that the strength of a Hydrogen bond in water (ca 16 kJ·mol –1) is about 3.5% as strong as an O–H intramolecular bond (459 kJ·mol –1). Students may not think that this is a big deal—but it is!!! It shows that an intermolecular force is not negligible compared to an intramolecular force. WebUse a dashed line to draw a hydrogen bond between ethanol (CH 3 CH 2 OH) and acetaldehyde (CH 3 CHO). Draw a box around the hydrogen bond donor and a circle around the hydrogen bond acceptor. The hydrogen bond should be drawn with an optimal hydrogen bond angle. 1 Start by drawing the structures of the molecules. 2 3 Next, …
