Which statement justifies that phosphine (PH3) is a polar molecule?
Weegy: Phosphine (IUPAC name: phosphane) is the compound with the chemical formula PH3. It is a colorless, flammable, toxic gas. [ Pure phosphine is odourless, but technical grade samples have a highly unpleasant odor like garlic or rotting fish, due to the presence of substituted phosphine and diphosphine (P2H4). With traces of P2H4 present, PH3 is spontaneously flammable in air, burning with a luminous flame. Phosphines are also a group of organophosphorus compounds with the formula R3P (R = organic derivative). Organophosphines are important in catalysts where they complex to various metal ions; complexes derived from a chiral phosphine can catalyze reactions to give chiral products. for more information check ] (More)

Which molecule is a dipole?
Weegy: Dipole moment may refer to: * Electric dipole moment, the measure of the electrical polarity of a system of charges * Transition dipole moment, the electrical dipole moment in quantum mechanics * Bond dipole moment, [ [ the measure of polarity of a chemical bond * Electron electric dipole moment, the measure of the charge distribution within an electron * Magnetic dipole moment, the measure of the magnetic polarity of a system of charges * Nuclear magnetic moment, the magnetic moment of an atomic nucleus * Molecular dipole moment, the electric dipole moment of a molecule. * Topological dipole moment, the measure of the topological defect charge distribution * The second order coefficient of the multipole expansion of a function ] ] User: Which molecule has a polar bond, but is nonpolar in nature? User: Which statement is true regarding methane and ammonia? User: In halogens, fluorine has fewer electrons and a weaker dispersion force as compared to iodine. Which statement is true regarding fluorine and iodine? Weegy: Fluorine has 7 valence electrons (More)

Based on the symmetry of the molecules, which is a polar molecule?
Weegy: The water is a polar molecule because it is not equally charged. [ [ Its half side has a positive charge and the other half has a negative charge because the electrons spend more of their time with the oxygen and not with hydrogen and due to this they get more negative charge and due to this the water is a polar molecule. ] ] (More)
