Question

16 question (3 points) each chiral center in a molecule can have either the r or s configuration - the presence of one chiral center leads to two possible configurational isomers. some c = c double bonds can also lead to two configurational isomers, the e and z configurations (these are referred to as stereocenters). the maximum number of configurational isomers that can exist for a molecule with n stereocenters is 2^n, representing each set of possible combinations of the configurations. 1st attempt part 1 (2 points) how many configurational isomers are possible for the following structure? part 2 (1 point) change the structure below to show the three - dimensional structure at the chiral carbons in the molecule. (only change the 3 - d structure at relevant carbon atoms; do not add any of the unshown hydrogen atoms).

Explanation:

Step1: Identify stereocenters

The given molecule has 2 chiral centers (carbons bonded to 4 different groups).

Step2: Use formula for number of configurational isomers

The formula for the number of configurational isomers for a molecule with \(n\) stereocenters is \(2^{n}\). Here \(n = 2\), so \(2^{2}=4\).

Answer:

4
