In TPR the question is how many steroisomers of aldohexoses exist.
Answer 2^n where n = # of chiral centers.
So... 2^4 = 16
Then it asks how many steroisomers of D-aldohexoses exist.
Answer = 2^3 = 8 because since you consider it D you only take into account the 3 other chiral centers.
Then EK asks a question, how many steroisomers of D-altrose are shown below. But it uses 2^4 and the answer is 16. Since its D shouldn't you use the formula 2^3?
Who is correct?
