Question
**Question:** Which of these would give a positive iodoform test? **Structures:** - **A:** Molecular structure resembling an aldehyde or ketone with the formula CH₃C(=O)CH₂CH₃. - **B:** Molecular structure resembling a ketone with the formula CH₃C(=O)CH(CH₃)₂. - **C:** Cyclic ether structure attached to an alkyl chain with hydroxyl group. - **D:** Propanol structure with formula CH₃CH₂CH₂OH. **Options:** - ○ B - ○ A - ○ A and D - ○ none of them - ○ D - ○ C - ○ A, C, and D **Analysis:** The iodoform test is used for the detection of methyl ketones or secondary alcohols with a methyl group on the carbon bearing the hydroxyl group. This test is positive for structures containing a CH₃C=O or CH₃CH(OH) group.
