317763 Assertion :
supporting img
Reason :
Principal functional group gets lowest number followed by double bond or triple bond.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.

2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.

3 Assertion is correct but Reason is incorrect.

4 Assertion is incorrect but Reason is correct.

Explanation:

supporting img
Since $- COOH$ is the principal functional group, it the gets lowest number than the secondary functional group (3-carbethoxy). So it is 3carbethoxy-2-butenoic acid. So, the option (1) is correct.
