The compound 3,4-diethylhex-3-ene can exhibit stereoisomerism due to its double bond and substituents. To determine the number of stereoisomers, one must consider both geometric isomers (cis/trans) and any chiral centers present. In this case, the final answer indicates that there are 4 possible stereoisomers for the compound."}
