Abstract:
In the first experiment the relative reactivity of various alkyl halides will be tested by placing them in acetone and ethanol. For solution (A) we added Sodium Iodide (NaI) in acetone, because its insolvable in acetone, and for solution (B)we added AgNO3 in ethanol, because again it is insolvable in ethanol. Three alkyl halides were then added to both solutions. After that we observed a white participate being formed in different quantities and colors some taking a long time to form and some not.
Introduction:
The goal of this experiment…show more content… The process is called nucleophilic substitution. Nucleophilic substitutions are divided in two groups: SN1 and SN2, the differences between the two are 1) that SN1 is a three step process, on the other hand SN2 is a one step process and 2) For SN1 the rate equation shows that its first-order dependence on electrophile and zero-order dependence on nucleophile and for SN2 it generates products stereospecifically with inversions of…show more content… To the test tube (A1) was added approximately 3 drops of 1-bromobutane, to (A2) 3 drops of 2-bromobutane and to (A3) 3 drops of 1-bromo-2-methylpropane. For the test tube A1 the white precipitate started forming in 2 minutes. For the reaction A2 and A3 the precipitate didn’t started forming after 10 minutes so It was heated a couple of times
In reaction (B) again three clean tubes were named B1,B2,B3 and 3ml of the solution were added using a glass pipet. And again to the test tube (B1) was added 1-bromobutane and to the test tube (B2) was added 2-bromobutane and finally to (B3) was added 1-bromo-2-methylpropane. For the test tube B3 it immediately precipitated and became grey. B2 precipitated really fast as did B1 but not as fast as the other two reactions.
Results:
The speed of the participate forming goes like this for reaction (A):
