Atif Saleem, Chem 3AL, Section 101 Discussion: Experiment 10, Nucleophilic Substitution Reactions of Alkyl Halides My partner was Jafar Mahmood in today’s experiment. In today’s lab, the purpose was to test the reactivities of several alkyl halides with two reagents: Sodium iodide in acetone, and ethanolic silver nitrate. We started out by testing sodium iodide in acetate which is an excellent nucleophile and favors SN2 reactions. 1) 1-bromopentane reacted by forming precipitate at the bottom. 2) 1-chloropentane gave no reaction, even though as a primary substrate it was predicted to. 3) 2-bromopentane became cloudy yellow upon heating. 4) 3-bromopentane reacted by forming precipitate upon heating. 5) 1-bromo-2-methylpropane reacted by forming a yellow precipitate upon heating for about 4 minutes. 6) 2-chloro-2-methylpropane gave no reaction. 7) 1-bromo-2,2-dimethylpropane turned bright yellow and remained that way. 8) bromocyclopentane reacted by forming precipitate upon heating. 9) bromocyclohexane only
