Homework Statement


A sample of synthetic camphor contains both the d and l isomers in unequal amounts . The specific rotation of the sample is found to be -13.9 degrees . What is the enantiomeric excess of the sample?

(A) 0.215

(B) 0.314

(C) 0.417

(D) 0.167

pleasez xplain ur working as well!

I too think that the question is lacking some info.

... unless your teacher actually expects you to do a little work and find the specific rotation of pure R or S camphor. Try the CRC Handbook. Even Wiki has it!

seeing ur reply makes me think whether this is reqd at JEE level??:-p
