In this experiment, the reactivities of various halogenoalkane, 1-bromobutane, 2-bromobutane, 1-chlorobutane, 2-bromo-2-methylpropane, and 1-bromo-2-methylpropane were tested using two different solutions, NaI in acetone and AgNo3 in ethanol. The rate of reaction, the carbocation stability of each substrate, and the identity of the leaving group could be used to determine the mechanism of a reaction. With NaI in acetone, primary halides, such as 1-bromobutane and 1-chlorobutane were the most reactive substrates, when bromine or chlorine is ionized. Also, the influence of a strong nucleophile (I-) and the steric hindrance as the main barrier to prevent or retard the reaction, make this reaction a second order-Sn2 mechanism. With AgNO3 in ethanol,
