Water is a polar molecule, while carbon tetrachloride is a nonpolar molecule. Within the extraction, a polar mixture is being separated in a polar solvent whereas a neutral or nonpolar … It is also known as N-phenylacetamide, acetanil, or acetanilid, and was formerly known by the trade name Antifebrin Preparation and properties. As the solvent evaporates, the acetanilide will remain. I am trying to understand what if polar or nonpolar analgesics would travel further in TLC. Molecular polarity depends on both individual bond polarities and molecular geometry, the latter of which we can … Join Yahoo Answers and get 100 points today. Median response time is 34 minutes and may be longer for new subjects. The impure acetanilide range was slightly higher than that of the purified with a range of 115°C-118°C. Why is phenol more polar than alcohol. Since the two -OH bonds in the salicylic acid molecule are close to two of the carbon atoms and far away from the other four, and since the molecule is asymmetric, salicylic acid is polar. acetanilide is a polar compound due to its amide group and other properties.
