from 110.8-114.0 °C‚ while the melting point range for benzoic acid is 121.0-123.0°C and 103.0-107.0°C for 4-amino acetophenone. Since the ranges we acquired for compound B are directly in between both acid and base melting points‚ we can conclude that the purity for compound B is relatively high due to the compound being made up of equal parts of benzoic acid and 4-amino acetophenone. Thus saying that our melting point ranges are fairly accurate because they exemplify an equal percentage of both

Once all three of the test tubes contained 2 mL of 5% NaOH and 3 drops of the unknown‚ 3-pentanone‚ or acetophenone‚ iodine solution was added by the drop until the yellow color of the iodine was slightly visible. The test tube containing the unknown and 3-pentanone only needed 3 drops each while acetophenone required 11 drops. The test tube containing acetophenone tested positive by forming a white/yellow precipitate at the bottom of the test tube. The unknown

Aliphatic hydrocarbons are divided into three classes: alkanes (e.g. methane‚ ethane and propane) have only single bonds‚ and are said to be saturated; alkenes (e.g. ethene and propene)
