During an experimental workup procedure, a chemist treated a starting material with NaoH in the solvent acetone `[(CH_(3))_(2)C=O]`, however, the starting material was recovered unreacted. Instead, the chemist isolated a small amount of product A (shown below).
Product A
1. Elemental analysis of product A indicated that it consisted only of carbon, hydrogen, and oxygen.
2. Product A had a molecular weight of 116 g/mol.
3. Product A was a methyl ketone because it gave a positive iodoform test.
4. When product A was treated with `Br_(2)` in `C Cl_(4)`, the red bromine colour persisted, because no carbon-carbon double bonds were present to react with the bromine.
The structure of product A was further confirmed when treatment with hot sulfuric acid resulted in the corresponding dehydration product, product (B)gt
Q. Wihch of the following compounds from the passage will give a positive iodoform test.?
A. Product A only
B. Product A and product B
C. Product A and acetone only
D. Product A, product B, and acetone.
