Q1. A forensic scientist is testing a solvent spill to confirm the presence of a methyl ketone. Which compound will produce a yellow crystalline precipitate with iodine and NaOH?
Answer: Acetone
Explanation: Acetone (a methyl ketone) gives a yellow iodoform precipitate; 3-pentanone lacks the CH3-CO group necessary for a positive iodoform test result.
