3. If a sample is determined to be 75% of the (+) enantiomer, then what is the enantiomeric excess? Answer question here I

Suppose compounds A and B are enantiomers.  What can be said about A and B (select all that apply). a. They are mirror images of eachother b. Neither contains a chiral center c. They consist of the same number & types of atoms d. They are superimposible e. They are NOT superimposable f. They are stereoisomers

There are 4 options

For the molecule below, a) Draw out every possible stereosimer.  b) Indicate any enantiomer pairs c) Then, indicate any meso-stereoisomers, and proceed to clearly indicate the internal mirror plane.
