Explanation / Answer
answer to 16
A DIASTEREOMERS
EXPLANATION
molecules that differ only in their spatial arrangement of atoms,carbon-carbon double bonds will exist as two different geometric diastereomers, if both of the double-bonded atoms have two different substituents. These diastereomers are differentiated with the designation cis and trans.
