In vacuum, the speed of light is c= 2.998 x 108m/s. However, the speed generally decreases when light travels through media other than vacuum. Then, the speed is approximately c divided by a quantity called the medium's refractive index (7). In which of the following, would the frequency of 210nm-light be the lowest? (c = 2v) (1) H2, n = 1.0001 (2) CCl4, n = 1.461 (3) H20, n = 1.3330 (4) silicone oil, n = 1.520 (5) diamond, n = 2.419

Amines are good nucleophiles, even though they are neutral molecules. how would the rate of an sn2 reaction between an amine and an alkyl halide be affected if the polarity of the solvent is increased? amines are good nucleophiles, even though they are neutral molecules. how would the rate of an reaction between an amine and an alkyl halide be affected if the polarity of the solvent is increased? because both reactants in the rate-limiting step are neutral, the reaction will be faster if the polarity of the solvent is increased. because both reactants in the rate-limiting step are neutral, the reaction will be slower if the polarity of the solvent is increased. because both reactants in the rate-limiting step are neutral, the reaction will occur at the same rate if the polarity of the solvent is increased. request answer
