Question

2 - pentanone and 3 - pentanone can be distinguished by : (A) Cannizaro’s reaction (B) Aldol condensation (C) Iodoform reaction (D) Clemmensen’s reduction

Tardigrade Admin · Accepted Answer

2-pentanone and 3-pentanone can be distinguished by iodoform test. CH3 COCH 2CH2 CH3 (2-pentanone) gives positive iodoform test while CH3 CH2 COCH2 CH3 (3-pentanone) does not give iodoform test.

Q. $2$ - pentanone and $3$ - pentanone can be distinguished by :

Cannizaro’s reaction

Aldol condensation

Iodoform reaction

Clemmensen’s reduction

$2$ -pentanone and $3$ -pentanone can be distinguished by iodoform test.
$C H_{3} COC H_{2} C H_{2} C H_{3}$ ( $2$ -pentanone) gives positive iodoform test while $C H_{3} C H_{2} COC H_{2} C H_{3}$ ( $3$ -pentanone) does not give iodoform test.
