How are there 8 stereoisomers for this molecule?
I though it was determined by 2 raised to the number of chiral
centers (2^n). However when looking at this molecule I thought that
there's only two chiral centers.There are 3 chiral centers (asymmetric carbons) in the given molecule, which are shown by asterisks.
So, there will be 23 = 8 stereoisomers possible for the given molecule, as shown below.
(i) (R, R, R)
(ii) (R, R, S)
(iii) (R, S, R)
(iv) (S, R, R)
(v) (R, S, S)
(vi) (S, R, S)
(vii) (S, S, R)
(viii) (S, S, S)

Consider the molecule shown below. ch_2ohchohchohch_3, Indicate chiral centers and predict the total number of stereoisomers. Draw them out in the Fischer projection. Build a model of one of them (orient it in the Fischer projection) so you can visualize the shape and how the chain curves. Sketch it to the best of your ability. Which of the molecules are enantiomers of each other? Are there any meso compounds? Justify your answers and draw them out. Take a pair of...
1. a) (2 points) The Fisher projection of molecule A reveals that it has three chiral carbons. What is the maximum number of stereoisomers that a molecule with three chiral carbons can have? b) (18 points) Even though molecule A has three chiral carbon atoms, there are only four stereoisomers: A, B, C, and D. Explain why so few stereoisomers exist, using structures as part our answer. Your answer should take your answer to a) into account. CH,OH CH2OH CH...

3. Diastereomers and Meso Forms. When a molecule has two or more stereogenic centers, stereoisomers that are not mirror images can exist; these are called diastereoisomers. Within this general class, there are special types of stereoisomers that are always optically inactive and are called meso forms. Construct a model with four different colored balls about a carbon center. Construct another identical to the first and verify this by the superimposition test. Now remove the same colored balls, blue (C from...
