13.9: Physical Properties of Alcohols; Hydrogen Bonding
WEBThe hydrogen bonding and dipole-dipole interactions are much the same for all alcohols, but dispersion forces increase as the alcohols get bigger. These attractions get stronger as the molecules get longer and have more electrons.
What intermolecular forces are present in alcohol? - Socratic
WEBMay 29, 2018 · Short chain alcohols have intermolecular forces that are dominated by H-bonds and dipole/dipole, so they dissolve in water readily (infinitely for methanol and ethanol). As the carbon chain gets longer, the contribution of the London dispersion forces becomes significant.
4.2 Intermolecular Forces - Chemistry LibreTexts
WEBIntermolecular forces are electrostatic in nature; that is, they arise from the interaction between positively and negatively charged species. Like covalent and ionic bonds, intermolecular interactions are the sum of both attractive and repulsive components. Because electrostatic interactions fall off rapidly with increasing distance between ...
9.4: Physical Properties of Alcohols, Ethers and Epoxides
WEBIn alkanes, the only intermolecular forces are van der Waals dispersion forces. Hydrogen bonds are much stronger than these, and therefore it takes more energy to separate alcohol molecules than it does to separate alkane molecules.
Intermolecular Forces - University of Wisconsin–Madison
WEBWhy are the intermolecular forces in ethanol stronger than those in ethyl ether? To answer this question, we must look at the molecular structure of these two substances.
10.1 Intermolecular Forces - Chemistry 2e - OpenStax
WEBIdentify the types of intermolecular forces experienced by specific molecules based on their structures; Explain the relation between the intermolecular forces present within a substance and the temperatures associated with changes in its physical state
Q: What are the intermolecular forces present in alcohol?
WEBAlcohol molecules exhibit three types of intermolecular forces: dispersion forces, dipole-dipole interactions, and hydrogen bonding. Hydrogen bonding, which is a special type of dipole-dipole interaction, is the strongest of these and has a significant effect on the physical properties of alcohols.
Alcohol - Boiling Point, Solubility, Flammability | Britannica
WEB(See chemical bonding: Intermolecular forces for a discussion of hydrogen bonding.) The oxygen atom of the strongly polarized O―H bond of an alcohol pulls electron density away from the hydrogen atom. This polarized hydrogen, which bears a partial positive charge, can form a hydrogen bond with a pair of nonbonding electrons on another oxygen atom.

WEBIn alkanes, the only intermolecular forces are van der Waals dispersion forces. Hydrogen bonds are much stronger than these and therefore it takes more energy to separate alcohol molecules than it does to separate alkane molecules.
17.2 Properties of Alcohols and Phenols - Organic Chemistry
WEBA positively polarized –OH hydrogen atom from one molecule is attracted to a lone pair of electrons on the electronegative oxygen atom of another molecule, resulting in a weak force that holds the molecules together (Figure 17.2). These intermolecular attractions must be overcome for a molecule to break free from the liquid and enter the ...
