CH3CN, Acetonitrile, is a polar molecule. With the triple bond between C and N, a negative charge weighs to the Nitrogen, while on the other "side" of the molecule the Hydrogen atoms tend to a...
Since the NH4^+1 ion has 4 H's attached to an N in a tetrahedral shape, it is nonpolarHowever Ammonia NH3 has 3 H's attached to an N in a pyramidal shape, so it is polarDo a search for Ammonium and...
