is 3-carbethoxy- 2-butenoic acid. Reason : Principal functional group gets lowest number followed by double bond or triple bond.

Options

  1. AIf both assertion and reason are true and reason is the correct explanation of assertion
  2. BIf both assertion and reason are true but reason is not the correct explanation of assertion
  3. CIf assertion is true but reason is false
  4. DIf both assertion and reason are false.

Correct answer

A. If both assertion and reason are true and reason is the correct explanation of assertion

Step-by-step solution

Assertion : is 3-carbethoxy- 2-butenoic acid. Reason : Principal functional group gets lowest number followed by double
Here since −COOH-\mathrm{COOH} is the principal functional group, it gets the lowest number than the secondary functional group (3-carbethoxy). So it is 3-carbethoxy-2-butenoic acid.
