a(3) molecular space configuration: generally speaking, the more symmetrical type space of molecules, and the intermolecular forces smaller.[translate] aH2O is polar molecule ,and O2 is non-polar molecule.[translate]
Why is HCl called a polar molecule? Explain your reasoning. Polar Molecules: A molecule is considered polar if it has an overall dipole moment. The dipole moment of the compound depends if the compound has polar bonds and if the geometry of the compound will permit a net dipole moment. Bo...
a== H2O == Water is H2O, 2 molecules of hydrogen and 1 molecule of oxygen. Water is slightly polar (has an electric charge). Surface tension and capillary action are the properties that result from polar water molecules. Surface tension is the property of water molecules clinging to each ...
A molecule will have dipole–dipole forces if it is polar. To determine whether a molecule is polar, (1) determine whether the molecule contains polarCONCEPTUAL PLAN

A polar molecule is mostly positive on one side and mostly negative on the other. This difference allows the polar molecule...
to the P atom than the bond pairs between P and H, there is consequently a slightly greater electron density and a slightly partial negative charge on the P atom (even as P and H have the same electronegativity), and hence a slight dipole moment, making PH3 a slightly polar molecule. ...
