MCQ
$IUPAC $ name of $C{H_3} - CH = CH - COOH$
- ✓$2-$ butenoic acid
- B$1-$ butenoic acid
- C$\beta$ - butenoic acid
- D$1-$ carboxy $ -1-$ propene
✓
Answer
Correct option: A.
$2-$ butenoic acid
a
${ }^4 CH _3{ }^3 CH ={ }^2 CH -{ }^1 COOH$
${ }^4 CH _3{ }^3 CH ={ }^2 CH -{ }^1 COOH$
But $-2-$ ene $-1-$ oic acid
