MCQ
Product of Perkin reaction is :
  • A
    $\alpha , \beta -$ unsaturated aldehyde
  • B
    $\beta -$ cyclohexyl $\alpha , \beta -$ unsaturated aldehyde
  • ✓
    $\beta -$ Aryl $-\alpha , \beta -$ unsaturated acid
  • D
    All 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.
