Which of the following precisely defined specific functional group structural motifs will definitive — Haloalkanes and Haloarenes Chemistry Question

💡 Solution & Explanation

The iodoform reaction accurately and strictly specifically tests positive exclusively for organic compounds completely securely containing the methyl ketone group ($CH_3-CO-$) directly, or secondary alcohols containing the $CH_3-CH(OH)-$ group, which are rapidly oxidized heavily in situ perfectly to methyl ketones by the active halogenating agent. Options C and D completely cleanly lack these required structural features.
