A sample of (–)-1-fluoro-2-methylbutane was analyzed in a polarimeter. The sample was prepared by dissolving 7.5 g of the compound to form a 50.0 mL solution and placing it in a 20 cm polarimeter tube. The observed rotation at 20°C is 0.173°. Calculate the specific rotation of (–)-1-fluoro-2-methylbutane.
