- ✓$\beta -$ Aryl $-\alpha , \beta -$ unsaturated acid
- DAll of these
✓
Answer
Correct option: C.
$\beta -$ Aryl $-\alpha , \beta -$ unsaturated acid
c
In Perkin reaction, an aromatic aldehyde condenses with acid anhydride in the presence of sodium salt of acid (from which acid anhydride is derived) to form $\beta$-aryl- $\alpha, \beta$-unsaturated acid.
