For making distinction between 2-pentanone and 3-pentanone, the reagent to be employed is:
$K_{2} C r_{2} O_{7} / H_{2} S O_{4}$
$Z n - H g / H C l$
$S e O_{2}$
$I o d i n e / N a O H$

Ketones having CH3CO-x2212- group give yellow coloured iodoform with I2 and NaOH-x2234-I2-NaOH is used to distinguish between 2-pentanone and 3-pentanone-

For making distinction between 2-pentanone and 3-pentanone, the reagent to be employed is:K2Cr2O7/H2SO4Zn−Hg/HClSeO2Iodine/NaOH

Ketones having CH3CO− group give yellow coloured iodoform with I2 and NaOH∴I2/NaOH is used to distinguish between 2-pentanone and 3-pentanone.

For making distinction between 2-pentanone and 3-pentanone, the reagent to be employed is:
$K_{2} C r_{2} O_{7} / H_{2} S O_{4}$
$Z n - H g / H C l$
$S e O_{2}$
$I o d i n e / N a O H$

Ketones having $C H_{3} C O -$ group give yellow coloured iodoform with $I_{2}$ and $N a O H$
$∴ I_{2} / N a O H$ is used to distinguish between 2-pentanone and 3-pentanone.
