Which one of the following compounds on treatment with

\mathrm{LiAl}{\mathrm{H}_4}

will give a product that will give a positive iodoform test?

View answer and explanation

Correct option: D

\mathrm{C}{\mathrm{H}_3}\mathrm{COC}{\mathrm{H}_3}

Option D (

\mathrm{C}{\mathrm{H}_3}\mathrm{COC}{\mathrm{H}_3}

) is correct because reduction of acetone with

\mathrm{LiAl}{\mathrm{H}_4}

gives isopropanol, which gives a positive iodoform test.
