Question

**Assignment: E/Z Configuration of Alkenes**

**Task**: Assign the E or Z configuration to the following alkenes.

**Structures:**

a) The first structure is a simple alkene with hydroxyl (OH) group attached to one carbon of the alkene double bond. The other carbon is bonded to a propyl group and a methyl group.

b) The second structure features a ketone and ester group on either side of the alkene's double bond. The ketone consists of a carbonyl group (C=O) bonded to a hydrogen, while the ester has a methoxy group.

c) The third structure includes a cyclopentyl ring that is bonded to one side of the alkene double bond. The other side contains an ester with a hydroxyl group.

d) The fourth structure contains multiple functional groups: a nitrile (N≡C), chlorine (Cl), and amine groups (NH₂). The alkene double bond lies between a methylene group and a carbon connected to a formamide group.

**Explanation for Assignment**:
The E/Z configuration refers to the stereochemistry of alkenes. "E" (entgegengesetzt) indicates that the highest priority groups on each carbon of the double bond are on opposite sides, while "Z" (zusammen) indicates they are on the same side.

To determine the configuration:
1. Identify the highest priority group on each carbon of the double bond, based on atomic number and connectivity.
2. Compare positions of the groups to assign E or Z configuration.
