part one has been answered. please answer part 2 only.

Question (3 points) Each chiral center in a molecule can have either the R or Sccafiguration - ae presenc of one chiral center leads to two possible configurational isomers. Some C=C double bonds can also lead to two con zurational isomers, the E und Zconfigurations (these are referred to as stereocenters). The maximum number of configurational isomers that can ex i for a molr ule with n siceocenters is 2n, representing each set of possible combinations of the configurations. 2nd attempt Part 1 (2 points) Hal See Periodic Table 0 See Hint How many configurational isomers are possible for the following structure? 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.)
