3pentenyl

3pentenyl refers to a substituent group derived from pentene, where the double bond is located between the third and fourth carbon atoms. This group has the chemical formula C5H9. Specifically, it is a five-carbon chain with a double bond at the 3-position and is attached to another molecule through one of its carbon atoms. There are two possible isomers for 3pentenyl depending on the stereochemistry around the double bond: (3E)-pentenyl and (3Z)-pentenyl. The (3E) isomer has the higher priority groups on opposite sides of the double bond, while the (3Z) isomer has them on the same side. This specific alkene functionality can participate in various organic reactions, such as addition reactions across the double bond, polymerization, and cycloaddition reactions. The properties and reactivity of compounds containing the 3pentenyl group will be influenced by the presence and position of this double bond.
