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
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 >
BrF5 or bromine pentafluoride is a polar molecule. The molecular geometry of BrF5 is square pyramidal with an asymmetric charge distribution. The molecule has a central bromine atom that is surrounded by five fluorides and a lone pair of electrons.Full Answer >
Xenon Tetraflouride, or XeF4, is a not a polar molecule. XeF4's geometric structure and symmetry causes the intramolecular forces within the molecule to cancel out, making XeF4 a non-polar molecule.Full Answer >
In general lipids are not polar; however the lipids that make up cell membranes are amphipathic, which means they have one non-polar end and one polar end. Cell membrane lipids are amphipathic in order to allow the cell membrane to be selectively permeable to compounds and atoms.Full Answer >
