Identify the three products formed when 2-bromo-2-methylpropane is dissolved in a mixture of 80% ethanol and 20% water.
Draw the structure of 2R 3R)-2,3-dichloropentane. Use bold or hashed wedges to indicate the configuration at asymmetric C atoms. Draw the molecule on the canvas by choosing buttons from the Tools (for bonds), Atoms, and Advanced Template toolbars. The single bond is active by default. Show the appropriate stereochemistry by choosing the dashed or wedged buttons and then clicking a bond on the canvas. 2 . H: 1200 mAh 31.+07 Marvin JS ChemAxon LADDODOOD
