So i have a quick question about the iodoform test. I thought that this was for determination of any aldehyde or ketone. I just did a question from the kaplan online material which asked, "which of the following will NOT produce a positive iodoform test?" ...and it showed several aldehydes, ketones and a primary alcohol as the choices. I assumed an alcohol wouldn't test positive, however the answer said that it would oxidize and form an aldehyde...therefore testing positive. The correct answer for "which of the following will not show a positive iodoform test," was benzaldehyde. My question is WHY??? Is it because it lacks an acidic alpha proton?
