Do an iodoform test. Use an aqueous solution of iodine and potassium iodide added to basic solutions of 2-pentanone and 3-pentanone.The iodoform reaction is a classical test for methyl ketones. A light-yellow precipitate of iodoform forms immediately with the methyl ketone of 2-pentanone.To confirm:1H NMR3-pentanone will show only 2 signals: a triplet at ~1.33 and a quartet at ~2.352-pentanone will show 4 signals: a triplet at ~0.90, a sextet at ~1.55, a singlet at ~2.05 and a triplet at ~2.40
2-pentanone IS a chemical. One place it's found is in tobacco.
The condensed structural formula for 1,3-dimethylcyclohexane is CH3-CH(CH3)-CH2-CH2-CH2-CH2.
The structural formula for 3-heptanol is CH3(CH2)5CH(OH)CH3. It has a chain of 7 carbon atoms with a hydroxyl group (OH) attached to the third carbon atom.
3-Pentanone does not give a positive iodoform test because it lacks the necessary structure. The iodoform test specifically requires the presence of a methyl ketone (a ketone with a methyl group adjacent to the carbonyl), which 3-pentanone does not have; its structure is CH3(CH2)3COCH3. Instead, it features a propyl group adjacent to the carbonyl, preventing the formation of iodoform (CHI3) upon reaction with iodine and a base.
A structural formula diagram of 3-chloro-2-methyl-1-butanol would include HO with a line drawn from it. Attached to the line would be offshoots which represented the methyl and butanol.
