Isopropyl alcohol, like all alcohols, is polar. It is polar because one of the properties of alcohol is hydroxyl, which forms hydrogen bonds and dissolves water molecules. Hydroxyl groups make electrons spend more time near the electronegative oxygen atom of the compound, so any compound with hydroxyl groups is polar.Know More
Isopropyl alcohol has a molecular formula of C3H8O. Because it is a polar compound, it can be used to dissolve a number of non-polar substances.
According to Ron Kurtis' School of Champions, an educational resource, polarity is the separation of electric charge in molecules that leads the molecules to have specific dipole or multipole movement. The polarity of a molecule is dependent on the difference in electronegativity between the atoms in the molecule. For polar substances like alcohol, the polarity is based on the chemical structure of the molecule.
Isopropyl alcohol contains hydroxyl groups, which are chemical groups formed by an oxygen atom with a covalent bond to a hydrogen atom. These groups can form hydrogen bonds with water molecules, which are also polar molecules. The structure of hydroxyl groups makes the electrons in the molecule spend more time near the oxygen atom, rather than the carbon or hydrogen atoms. The oxygen atom is electronegative. This collecting of electrons near the oxygen atom is what makes the compound polar.Learn more about Atoms & Molecules
Isopropyl alcohol, also known as rubbing alcohol, expires no sooner than two years after opening when properly stored. Proper storage includes a secure, dry container in a cool, well-ventilated area.Full Answer >
Hydrogen chloride is a polar molecule because it contains a polar, covalent bond between hydrogen and chlorine. This gives the hydrogen a partial positive charge and the chlorine a partial negative charge.Full Answer >
NCl3 is a slightly polar molecule. This is because nitrogen has a lone pair of electrons that repels the bonded electron pairs of the N-Cl covalent bonds, thus giving the molecule an asymmetric structure where the polarities of the bonds do not cancel each other out.Full Answer >
Carbon dioxide, or CO2, is a nonpolar molecule. The molecule has a linear geometry due to the molecular arrangement of the compound. It is arranged with a central carbon molecule and two oxygen atoms surrounding the carbon atom.Full Answer >
