Join Yahoo Answers and get 100 points today. Assume that covalent bonding is not an intermolecular forces and only put in London dispersion forces, dipole-dipole and hydrogen bonding. Which bonds or forces are broken when ethanol is vaporized? Covalent bonding occurs between two non-metallic atoms characterized by the sharing of electron pairs between the atoms and other covalent bonds with electronegativity difference is greater than 2.0 (<2.0).
Based on the choices, I would suggest that the original question should not have mention intermolecular forces, but referred to bonds in general. Calculate the mass in grams of O2 at -34 oC?

What types of intermolecular bonding are present in ethanol, C2H5OH(l)? Covalent bonding results in the formation of molecules or giant structures. This is a weak form of attraction that holds the C2H5OH molecule together, and can easily be broken by a polar solvent such as water. London dispersion forces - yes, all molecules exhibit London dispersion forces. Consider the most stable excited state of N2.? Imiz has omitted London dispersion forces which are present between ALL molecules. Can we get to 10,000 posts before Halloween? For example, how is C2H5OH a simple molecular structure? Both have molecular formulae, which tells you how many atoms there are in the molecule. 0. reply. Covalent bonds, on the other hand, appear to involve two atoms sharing electrons reach a more stable electron configuration.Some compounds contain both ionic and covalent bonds.These compounds contain polyatomic ions.Many of these compounds contain a metal, a … 1- Every compound that are formed between metal atom and non metal atom are ionic in nature.
