Witryna17 gru 2013 · II) SiO2 is a covalent network solid so the entire structure of one macromolecule is held together with strong covalent bonds. NF3 is held together with dipole dipole forces and they are much weaker than covalent bonds, less energy is required to sever those IMFs. B) I) NH3 is London and H bond and CH4 has London WitrynaThe polar covalent bond is much stronger in strength than the dipole-dipole interaction. The former is termed an intramolecular attraction while the latter is termed an …
