A) compound containing an aldehyde and a ketonic group
B) \[\alpha \], P-unsaturated acid
C) \[\alpha \]-hydroxy aldehyde
D) \[\alpha \]-hydroxy ketone
Correct Answer: D
Solution :
Benzaldehyde when heated with ethanolic KCN, it gives \[\alpha \]-hydroxy ketone, benzoin. \[\underset{Benzaldehyde(2mol)}{\mathop{{{C}_{6}}{{H}_{5}}CHO+H-\overset{\begin{smallmatrix} O \\ || \end{smallmatrix}}{\mathop{C}}\,-{{C}_{6}}{{H}_{5}}}}\,\xrightarrow[\Delta ]{alc\,\,KCN}\] \[{{C}_{6}}{{H}_{5}}CH\underset{Benzoin}{\mathop{(OH)\,\,\overset{\begin{smallmatrix} O \\ || \end{smallmatrix}}{\mathop{C}}\,-{{C}_{6}}{{H}_{5}}}}\,\]You need to login to perform this action.
