Abstract By adding HCl to 2-methyl-2-butanol‚ through the Sn1 mechanism‚ 2-chloro-2-methylbutane is formed. Water‚ sodium bicarbonate and NaCl(aq) were then added to the 2-chloro-2-methylbutane to remove any of the excess water from the reaction. To confirm‚ a successful reaction‚ AgNO3 was added to the 2-chloro-2-methylbutane. A white precipitate formation confirmed a successful Sn1 reaction. Introduction Nucleophilic substitution reactions such as Sn1 and Sn2 allow us to convert one functional
