Solution: A forensic chemist (chemist who deals with crime-related investigations) analyzed a sample of a poisonous alkaloid (generic term for a naturally occurring nitrogen-containing molecule) and determined that its specific rotation [α] at 25 °C using sodium D light was + 12 °. What can the chemist properly conclude?  a) there is one enantiomer in the sample b) the enantiomer present has the R configuration c) the sample is optically pure d) the butler did it e) none of the above
