The ester with the common name "ethyl crotonate" has the formula CH₃CH=CHCOOCH₂CH₃. There is a trans C=C double bond between C-2 and C-3 of the acid portion of the ester. The acid itself is named but-2-enoic acid. We could indicate stereochemistry by calling it trans-but-2-enoic acid, but the Cahn-Ingold-Prélog E/Z notation is preferred.
