The compound 6-chloro-9-ethyl-2-methylundeca-3,7-dien-5-ol contains chiral centers and double bonds, which contribute to its stereoisomer count. By analyzing the structure, we find that the total number of stereoisomers is 16, taking into account both the chiral centers and the geometric isomerism from the double bonds."}
