An electrical dipole consists of two opposite charges attached to a molecule and separated by a certain distance. An attraction of the charges is prevented by the rigidity of the molecular structure. The potential produced by the dipole will be different from that produced by a single charge. WebThe point group of crown-6 is S6. The dipole moment of crown-6 varies in different solvent and under different temperature. Under 25 °C, the dipole moment of crown-6 is ± D in cyclohexane and ± in benzene.[2] The synthesis of the crown ethers led to the awarding of the Nobel Prize in Chemistry to Charles J. Pedersen. dipole (plural dipoles) (physics) Any object (such as a magnet, polar molecule or antenna) that is oppositely charged at two points (or poles). (chemistry) Any molecule or radical that has delocalised positive and negative charges. (radio) A dipole antenna. Derived terms [ edit] show Derived terms Translations [ edit]. electric dipole, pair of equal and opposite electric charges the centres of which are not coincident. An atom in which the centre of the negative cloud of electrons has been shifted slightly away from the nucleus by an external electric field constitutes an induced electric dipole. When the external field is removed, the atom loses its dipolarity. A water molecule (H 2 O), in which two hydrogen atoms stick out on one side and form together with the oxygen atom as vertex a ° angle, constitutes a permanent electric dipole. The oxygen side of the molecule is always somewhat negative .

Jan 1,  · 2. The reactivity of amines is generally based on how nucleophilic they are. In turn, their nucleophilicity is dependent upon how much of the nitrogen lone pair of electrons really exists on the nitrogen atom (e.g. the lone pair electron density on nitrogen). In ammonia (N H X 3), the lone pair electron density on nitrogen is very high. and "weak bonds" or "secondary bonds" such as dipole–dipole interactions, the London dispersion force and hydrogen bonding. Strong chemical bonding. Sep 28,  · Dipole moments occur in any system in which there is a separation of positive and negative electrical charges; therefore, they can be found in both ionic and covalent bonds. A dipole moment is a result of unequal electron distribution, which occurs due to differences in electronegativity between chemically-bonded atoms (since electrons tend to. 1. a.: a pair of equal and opposite electric charges or magnetic poles of opposite sign separated especially by a small distance. b.: a body or system (such as a molecule) having such charges or poles. a radio antenna consisting of two horizontal rods in line with each other with their ends slightly separated. dipolar.
