i. Fоr the given chemicаl reаctiоn belоw on (R)-2-butаnol, give chemical name and the (R/S) configuration of the product. ii. Indicate the limiting reagent and calculate the theoretical yield (in grams) of the product if 4.8 g of (R)-2-butanol (mm=74.12 g/mol) was reacted with 10.09 g NaBr (mm=102.89 g/mol) in presence of excess concentrated H2SO4. Atomic weights: (C = 12.01, H = 1.01, O = 16.00, Br = 79.91) iii. Calculate the percent yield if only 8.00 g of the product was obtained.
