1.	What is the correct name of the following compound?(a) D-(+)-fructose(b) D-(-)-fructose(c) L-(+)-fructose(d) L-(-)-fructoseThe question was asked during an interview.This interesting question is from Biomolecules Carbohydrates topic in division Biomolecules of Chemistry – Class 12
Answer» Right answer is (b) D-(-)-fructose The best I can explain: SINCE the OH GROUP on the carbon ADJACENT to the last CH2OH group is on the right-hand SIDE, it is of D configuration. Also, fructose is naturally a laevorotatory compound, HENCE the (-) sign.
