Short Answer

Question: Label each carbon-carbon double bond in 11-cis-retinal as E or Z. As we will learn in Section 21.11, the isomerization of one double bond in this compound to a less crowded stereoisomer takes place when light strikes the retina of the eye.

Answer

E and Z configuration in C=C bonds

See the step by step solution

Step by Step Solution

Step 1: E and Z naming

E and Z naming is used to differentiate two stereoisomers when the double bond is surrounded by more than two types of alkyl groups.

Step 2: Stereoisomers

These are the molecular compounds with the same bonding but different spatial arrangement or linkage of atoms.

Step 3: Labeling the given compound as E or Z

E and Z configuration in C=C bonds
