A) This compound is chiral.
B) The enantiomer of this compound is (3S, 4S) -3,4-dimethylhexane.
C) This compound is a diastereomer of (3R, 4S) -3,4-dimethylhexane.
D) all of the above
E) none of the above
Chiral
Describes a molecule that is not superimposable on its mirror image, often leading to different reactions or interactions for each form.
Diastereomer
Molecules that are stereoisomers, not mirror images of each other and have more than one chiral center.
- Determine the structural correlations between different types of stereoisomers, including enantiomers, diastereomers, geometric isomers (cis-trans), and meso compounds.
- Utilize the principle of chirality, specifically chiral centers and stereocenters, to evaluate optical activity within molecules.

Final Answer :
D
Explanation :
The compound is chiral because it has two chiral centers (carbon atoms with four different groups attached), making statement A true. The enantiomer of a chiral compound has the opposite configuration at all chiral centers, making statement B true for (3S, 4S)-3,4-dimethylhexane. Diastereomers are stereoisomers that are not mirror images of each other, which applies to (3R, 4R)-3,4-dimethylhexane and (3R, 4S)-3,4-dimethylhexane, making statement C true. Therefore, all statements are correct.
