In a smaller molecule, there is less hindrance around the polar bonds, making intermolecular bonding stronger. How do intermolecular forces affect surface tension and viscosity? Hydrogen bonds form when you have a negative O, N, or F atom in one molecule and a positive H atom attached to an O, N, or F atom in another molecule. The electronegativities of C and H are so close that C-H bonds are nonpolar. It is a blob with no positive or negative ends. Ethanol (\(\ce{C2H5OH}\), molar mass 46) boils at 351 K, but water (\(\ce{H2O}\), molar mass 18) boils at higher temperature, 373 K. This is because: water has stronger London dispersion forces. This implies that HF is more polar and possess stronger hydrogen bonds than HCl molecules. For example, the average bond-energy for \(\ce{O-H}\) bonds in water is 463 kJ/mol. WebA liquid with weak intermolecular forces evaporates more easily and has a high vapor pressure. A liquid's vapor pressure is directly related to the intermolecular forces present between its molecules.
