Acetone is a good solvent due to its ability to dissolve both polar and nonpolar substances, while other solvents can only dissolve one or the other. Secondly, acetone is a good solvent because it is miscible substance, meaning it has the ability to mix with water in all proportions.
This allows acetone to be added to water to help dissolve chemicals in a scientific setting. Acetone is organic, non-toxic, and incredibly versatile, making it a necessary solvent for activities spanning from cleaning and sterilizing, to extraction and chemical studies. Acetone is a good solvent, that can be used in a multitude of products and industries. Nail polish remover commonly contains a chemical called acetone.
It is a well known substance that is good for dissolving many things, some of which are in nail polish. The size of acetone is very small, which makes it easily integrable into the spaces of the larger molecules in nail polish. In fact, acetone is used as one of the solvents for nail polish such that nail polish stays in liquid form. When the polish is applied to a nail, the acetone evaporates quickly, and the polish becomes dry. The large molecules in the polish now interact more strongly with one another and becomes a solid film.
This process applies to other substances used as nail polish removers, such as ethyl acetate and isopropyl alcohol. Strictly speaking, the interaction between the polish and the remover is not a chemical one - no chemical bonds are broken or formed in the process; the dissolving process is only physical. The active ingredient in nail polish remover is acetone chemical formula C 3 H 6 O.
The reaction which occurs is a dissolution reaction , which is a reaction, but different from a chemical reaction. The acetone gets between the polymer chains of the polish, breaking up the polish and suspending the molecules in a liquid which can easily be wiped off. The atoms that are covalently bonded to each other form a polar bond if both atoms differ in their electronegativity. More electronegative atom attracts the bonded electron pair slightly more towards it and gains partial negative charge on it.
Basically, the unequal distribution of charge among the atoms of a molecule makes it polar in nature. You can check out the reason for the polarity of HBr. Nonpolar Molecules : These molecules have zero dipole moment. The atoms in this molecule share an equal proportion of charge. The covalent bond formed by atoms is said to be nonpolar if both atoms have equal electronegativity. Few examples of such molecules are Hexane, PCl5, etc.
You can check out the reason for the non-polarity of PCl5. Acetone is an organic compound made up of 3 carbon atoms, 6 hydrogen atoms, and 1 oxygen atom. The molecule consists of one carbonyl group surrounded by two methyl groups on both sides. The methyl group on both sides of the carbonyl group is nonpolar but the carbonyl group is polar in nature because of the difference between the electronegativity of oxygen and a carbon atom.
If we calculate the difference between the electronegativity across the carbonyl group. It turns out to be 3. Electronegativity : The term electronegativity is defined as the strength to attract the bonded electron pair towards its side. If there is a difference between the electronegativity of two atoms forming a covalent bond. Higher electronegative atom attracts the bonded electron slightly towards its side and gains a partial negative charge.
Therefore, the polarity of a molecule is directly proportional to the difference between the electronegativity of atoms forming that molecule. Dipole Moment : The dipole moment is the measure of the polarity of a molecule.
The dipole moment is denoted by D. Its SI unit is Debye. The polar molecule always has a non zero dipole moment. And the nonpolar molecules have zero dipole moment. Geometrical Shape : The shape of a molecule is an important parameter to check whether a molecule is polar or not.
The methyl groups are nonpolar but the carbonyl group is polar in nature because of the difference between the electronegativity of oxygen and carbon atoms. Guys, if you have any questions regarding the polarity of acetone. You can ask them in the comment sections.
