What is different between polar and non-polar molecules?
A polar molecule is one that has a negatively charged end and a positively charged end, which form poles. A non-polar molecule doesn't.
Is the cholesterol molecule mostly non polar or polar and why?
It is MOSTLY non polar because it has 27 carbons arranged in several ring structures, and a side chain. This makes it non polar. The only polar parts of the molecule is an -OH group on one of the ring structures.
A molecule with opposite charges on opposite ends?
This describes a polar molecule, which has a positive charge on one end and a negative charge on the other due to an uneven distribution of electrons. Water is an example of a polar molecule, with the oxygen end being slightly negative and the hydrogen ends being slightly positive.
How do polar molecules differ from non-polar molecules?
Polar molecules have positive charge on one side and negative charge on other side. Non polar molecules have covalent bond and do not have positive and negative charge on one or other side of the molecule.
Is the molecule SiS2 polar or nonpolar?
It is a non-polar covalent molecule This is because Silicon has 4 electrons in its valence shell While Oxygen only has two When you put 2 oxygen together with one Silicon , all the electrons are then equally shared making it non-polar.

What is polar and not polar?
A polar molecule, like water, is one that has a slight positive charge on one side and a slight negative charge on the other. A non-polar molecule, like a lipid, is one that has a neutral charge throughout.
A molecule with opposite charges on opposite ends?
This describes a polar molecule, which has a positive charge on one end and a negative charge on the other due to an uneven distribution of electrons. Water is an example of a polar molecule, with the oxygen end being slightly negative and the hydrogen ends being slightly positive.
Is acetylsalicylic acid or aspirin non-polar polar or ionic?
aspirin is non-polar, although it does have one alcohol group. The molecule is still considered non-polar due to the larger section of non-polarity. it will have a slight dipole, but probably not enough to hydrogen bond.
PCl3 polar or non polar?
PCl3 has a pyramidal geometry, with three polar P-Cl bonds and one lone pair of electrons. Hence the molecule is polar.
How do polar molecules differ from non-polar molecules?
Polar molecules have positive charge on one side and negative charge on other side. Non polar molecules have covalent bond and do not have positive and negative charge on one or other side of the molecule.
Why does hexane not form a solution with water?
Water is a polar molecule (is a dipole, has a positive end and a negative end), hexane is a non-polar molecule. Like dissolves like. Water will dissolve other polar molecules, like HCl and NH3. Hexane will dissolve non-polar molecules like benzene or toluene.
Can a molecule be polar with no polar covalent bonds?
No, not necessarily. It all depends on the symmetry of the molecule. Take a look at Carbon dioxide. It has a linear shape like this : O=C=O Although the bonds are obviously polar, the molecule is symmetrical. This makes the polarities of the bonds "cancel" each other, so to speak. So overall, this molecule is non-polar. If you take a look at Hydrogen chloride, on the other hand, it has a shape like this: H-Cl The molecule is assymmetrical, so this is a polar molecule.
Is the molecule SiS2 polar or nonpolar?
It is a non-polar covalent molecule This is because Silicon has 4 electrons in its valence shell While Oxygen only has two When you put 2 oxygen together with one Silicon , all the electrons are then equally shared making it non-polar.
Is nl3 polar or non polar?
NL3 (nitrogen trifluoride) is a polar molecule. This is because the nitrogen atom has a higher electronegativity compared to the fluorine atoms, leading to an uneven distribution of charge within the molecule.
Is pf3 polar or nonpolar?
PH3 is a non-polar covalent molecule. This is somehow confusing because, when you draw out the Lewis diagram, you will observe a lone pair on the P atom. However, if the electronegativity difference does not have a polar bond, then no matter what happens, it will always be non polar. In this case, the EN is 0.01, which indicates non polar. (Non polar EN is 0~0.4)To decide whether a molecule is polar or non-polar, first draw the Lewis diagram. Then calculate the electronegativity. If the electronegativity is non polar, then no matter it has lone pairs or it has more than one group around the central atom, it will always be non polar. In this case, PH3 is non polar because of it has a non polar bond indicated by the electronegativity even though it has lone pairs.But if the bond is polar, then you might have a chance to get a polar molecule depending on either of these 2 factors:1. If there are lone pairs2. If there are other groups around the central atomFor example, H2O is polar because:1.It has a polar bond for electronegativity2.It has lone pairs(Even if it doesn't have a other groups around the central atom, it's still polar because it's polar if you just satisfy either of the 2 conditions)If both conditions of the above are not met, then it's non polar even if it has a polar bond. Like CO2, a molecule has a polar bond, but fails to meet both of the conditions, is a non polar molecule.Always remember to check your electronegativity. Remember if a molecule only has non polar bonds, then it must be a non polar molecule no matter which condition is satisfied after (ex. lone pairs). If a molecule has polar bonds, then it may be a polar molecule depending on either of the 2 conditions listed.
