WebThere are two H-bonding interactions for H-bond donors. The strongly electronegative elements (primarily nitrogen, oxygen, and fluorine) will always form a relatively large partial negative charge when bonded with carbon. These elements can accept H-bonds when they are part of the organic molecule. WebEach molecule participates in something around 3.5 hydrogen bonds, on average. This might make you think the enthalpy of vaporization should be 23 * 3.5 = 80 kJ/mol.
