You can check out the reason for the non-polarity of BF3. Jupiter is a massive planet as compared with the earth with ammonia crystals covering its surface due to very low temperature. Dipole Moment: the dipole of a molecule is the measure of its polarity. If there is a difference between the electronegativity of atoms involved in a molecule, the molecule formed is polar in nature. initial pressure (P1) = 1.17 atm Around the nitrogen centre there are EIGHT electrons involved in covalent bonding: 2*"electrons" in the N-O and N-Cl bonds.and 4*"electrons" in the N=O bond. For example, if the molecule were and you decided the hydrogen atom was closest to the negative side of the molecule, you'd enter H at the latest coulumn. Depending on how many electrons are involved in the bond of the molecule, it may be single, double, or triple in organic molecules. Dipole moments, for example, do not exist in molecules that can be mirrored/flipped around a molecular geometric plane because dipole moments are only a single point.
