Please understand that polar or nonpolar is a continuous range, not an either or. Relevance. Each bond has polarity (though not very strong). Also, it is known that water is a polar solvent and like dissolves like. Other examples of polar chemicals include alcohol and vinegar. Oil doesn't stay dissolved because the water molecules are polar and are strongly attracted to each other to the point that the oil molecules are excluded. Oils repel polar molecules such as those found in vinegar. Gasoline is nonpolar. Vinegar or acetic acid is a polar molecule whereas oil is a chain of hydrocarbons which are insoluble in water. not vinegar as a substance, but the molecule. The -OH groups are polar. The bonds are arranged symmetrically so there is no overall dipole in the molecule. Oil is nonpolar. In table two, indicate whether the solutes (vinegar and iodine solution) are soluble in the solvent (water). Therefore, vinegar being polar will dissolve in polar solvent like water. Is a vinegar molecule polar or nonpolar? "Like" dissolve "like". If you believe it will, then it will be non-polar. Examples of non-polar solvents: carbon tetrachloride (CCl4), benzene (C6H6), ... Vinegar, for example, is a solution of acetic acid in water. In the methane molecule (CH 4) the four C−H bonds are arranged tetrahedrally around the carbon atom. Then conclude whether the compound is polar, nonpolar, or ionic. It is 4-5% acetic acid dissolved in water and that is polar. 8 years ago. Favorite Answer. A polar molecule has a positive charge on one end and a negative charge on the opposite end. (Hint: Like substances dissolve like substances, and polar solvents dissolve ionic compounds.) Non-polar solvents are liphophilic as they dissolve non-polar substances such as oils, fats, greases. 1st Liberal. Vitamin A is polar. vinegar is polar. If the ink is attracted to oily fingers, then it is nonpolar. Vinegar is polar. Many nonpolar organic solvents, such as turpentine, are able to dissolve non-polar substances. Mix the contents with a stirring stick. Polar chemicals generally are soluble in water. However, polar and non polar chemicals do not mix. Lv 6. Ethanol is polar. Where the carbons are bonded, and the center carbon has a double bond to on oxygen, and a single bond to another but the one with the single bond has an H. Nail polish is polar. By the way, if it dissolves in water, that is a good bet that it is polar. Then conclude whether the compound is polar, nonpolar, or ionic. Vinegar is basically a water solution of acetic acid. The molecule is CH3 - COOH. Mix the contents with a stirring stick. Fat is nonpolar. This is where the saying “like oil and water” comes from. Vitamin C is polar. One way to think about it is to observe (or postulate) that it will mix with oil. and why? 3 Answers. 3. Hydrocarbons are nonpolar. The polar particles of salad oil are attracted to the nonpolar particles of the vinegar. Oil is nonpolar. On the other hand, oil being non-polar does not dissolve in polar solvent like water. In table two, indicate whether the solutes (vinegar and iodine solution) are soluble in the solvent (water). It is polar, any time you have something with a lone pair, you can bet it will be polar unless you have some crazy dipole cancellations. Iodine solution Vinegar No Ionic Nonpolar Vegetable oil Vinegar Yes Nonpolar Nonpolar Conclusion Write a conclusion statement that addresses the following questions: Due to Covid-19 pandemic, I used the internet to research the answers to this lab, so that is how I determined the polarity of these substances. Dry-cleaning solvents are polar. Anything that can't, is non polar. Because oils also repel water, they are called hydrophobic, which means “water-fearing.” The carbon (black) and hydrogen (white) in this non-polar fatty acid molecule share electrons evenly and are neither negatively or positively charged. (Hint: Like substances dissolve like substances, and polar solvents dissolve ionic compounds.) Oil based paints are nonpolar. Answer Save. 3.
