    Intermolecular forces in BF3

    Hi! Boron trifluoride is a nonpolar molecule due to its high symmetry even though the covalent bonds within the molecule are polar. As a result, the only type of intermolecular forces in BF3 would be the London dispersion forces. I understand that these forces are exhibited by nonpolar...

    A quickie... predicting intermolecular forces

    Which one is more soluble in CF4? O2 or N2? Using geometry and intermolecular forces rules... My guess... "CF4 is a tetrahedrical, nonpolar compound, so he has only "london dispersion forces" N2 is nonpolar, only with london and so O2. So the thing to compare is Molecular mass, Mr(N2)=28...

    Intermolecular forces and penicillin help??

    Hi all I am stuck on the following question the question regards a penicillin G R-grop (a benzyl group C6H5CH2) and the amino acids Leucine HO2CCH(NH2)CH2CH(CH3)2 and Serine HO2CCH(NH2)CH2OH . what type of intermolecular attraction that you would expect the ‐R group of penicillin‐G to form to...

    intermolecular forces and melting point relationships?

    This is the question: Arrange the following in order from highest to lowest melting points. Explain your arrangement based on structure and bonding principles. N2, SiO2, Cl2, H2O, NaF, KCl. based on values I found elsewhere the order should be SiO2, NaF,KCl, Cl2, N2, H20 However I am not...
