1,4-Pentene acid, also known as 4-pentenoic acid, is an unsaturated carboxylic acid with a pentene chain. The structural formula can be represented as follows:
H H H O
| | | ||
H — C — C — C — C — C — OH
| | |
H H H
In a more linear representation, the structural formula can be written as:
CH2=CH-CH2-COOH
This shows that there is a double bond between the first and second carbon atoms (from the carboxylic acid end), leaving the carboxyl group (-COOH) at the terminal end of the chain.
