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

If We Had Known About Green Chemistry In 1951‚ How Would Things Be Different Today? Green Chemistry is the making of chemical products that reduces or eliminates the use and production of hazardous substances in the designing‚ making‚ and use of chemical products. It involves the designing and re-designing of chemical creation and chemical products to prevent pollution which will therefore solve environmental problems. Green Chemistry is environmentally safe and has very little side effects on
