What is the moral lesson of at wars end by rony diaz? 2 How do you tell if its an ionic or molecular compound? a). Glucose has a lot of OH parts so there is a lot of H-bonding possible, which is the strongest of the intermolecular forces and will dominate the rest. Shape: bent. This means one has very few atoms in their outer shell, while the other has many. Glucose is a bent shape because the molecule is not symmetrical. It is an Ionic bond. Dipole is permanent, so the attraction is stronger. Simple molecular substances are gases, liquids or solids with low melting and boiling points. Sugar is a conductor of electricity. When this happens, the electrons are still shared, but they tend to spend more time ar Your email address will not be published. Question = Is BrF polar or nonpolar ? The main difference between covalent and ionic bonds is that ionic bonds occur between two species which are electrostatically attracted towards each other, whereas covalent bonds occur covalently through the sharing. https://en.wikipedia.org/wiki/Ionic_bonding.
