Vedclass · Answer

(A) Isobutyraldehyde is an aldehyde,which can be oxidized to the corresponding carboxylic acid (isobutyric acid) using oxidizing agents.$HNO_3$ is a strong oxidizing agent.$2[Ag(NH_3)_2]^+$ (Tollen's reagent) is a mild oxidizing agent that specifically oxidizes aldehydes to carboxylic acids.$NH_2NH_2 / OH^-$ (Wolff-Kishner reduction) reduces aldehydes to alkanes.$NaOH$ typically causes aldol condensation or Cannizzaro reaction (if no $\alpha$-hydrogen is present) but does not oxidize aldehydes to acids.Therefore,reagents $I$ and $III$ are the correct oxidizing agents.

$I. HNO_3$	$II. NH_2NH_2 / OH^-$
$III. 2[Ag(NH_3)_2]^+$	$IV. NaOH$

Which of the following reagents will convert isobutyraldehyde to the corresponding acid?
$I. HNO_3$ $II. NH_2NH_2 / OH^-$
$III. 2[Ag(NH_3)_2]^+$ $IV. NaOH$
