Q. 2-pentanone and 3-petanone can be distinguished by
A) Cannizaro’s reaction
B) Aldol condensation
C) Iodoform reaction
D) Clemmensen’s reduction
Explanation
(c)
2-pentanone and 3-pentanone can be distinguished by iodoform test.
$CH_{3}COCH_{2}CH_{2}CH_{3}$(2-pentanone) gives positive iodoform test while $CH_{3}CH_{2}COCH_{2}CH_{3}$ (3-pentanone) doesn’t give iodoform test.
