are surfactants polar or nonpolar?

A surfactant molecule posses both a polar “water-loving” headgroup attached to a non-polar “water-hating” (or “oil-loving”) tail. Due to their dual nature, they are associated with many useful interfacial phenomena, and as such are key components for many diverse industrial products and processes.

C2Br2 : If we look at this structure then there is symmetry in it. Due to this symmetry dipole moments of 4 C-Br bond is cancelled and resultant dipole moment of the molecule is 0. Therefore molecule is non polar.

Carbon tet is nonpolar. A good solvent for NaCl would be polar and the negative end of the solvent would surround sodium ions and the positive end would surround chloride ions.

polar/nonpolar? Put the following in order from greatest to least intermolecular forces: H2O, LiOH, CO2. explain your reasoning. Since the bonds are polar covalent by their electronegativities but the molecule is nonpolar, london dispersion is the greatest because it is nonpolar.

Covalent compounds are non polar. And almost all organic compounds are non polar. According to the rule of the thumb- 'like dissolves like', covalent compounds are soluble in organic solvents.

The phosphate group is the negatively-charged polar head, which is hydrophilic. The fatty acid chains are the uncharged, nonpolar tails, which are hydrophobic. Since the tails are hydrophobic, they face the inside, away from the water and meet in the inner region of the membrane.

Both stearic acid (a fatty acid) and phosphatidylcholine (a phospholipid) are composed of chemical groups that form polar “heads” and nonpolar “tails.” The polar heads are hydrophilic, or soluble in water, whereas the nonpolar tails are hydrophobic, or insoluble in water.

Hexanol is mostly non-polar with a some polar properties: The electrostatic potential clearly shows that the oxygen is partially negative. When compared to the methanol and propanol, the total of six carbons and and multiple hydrogens shows the dominance of the non-polar properties by the large amount of gray areas.

Both polar and nonpolar molecules are found in covalent substances. Some covalent molecules have the ability to get polarized and some do not. ... Polar molecules interact with each other by forces such as dipole-dipole interactions whereas nonpolar molecules interact with each other through London dispersion forces.

A non-ionic surfactant has no charge groups in its head. The head of an ionic surfactant carries a net charge. If the charge is negative, the surfactant is more specifically called anionic; if the charge is positive, it is called cationic.

For example, ionic compounds, which are very polar, are often soluble in the polar solvent water. Nonpolar substances are likely to dissolve in nonpolar solvents. ... Polar substances are not likely to dissolve to a significant degree in nonpolar solvents. For example, ionic compounds are insoluble in hexane.

NaHCO3 (sodium bicarbonate) is neither polar nor non-polar in its pure form because it is not a covalent compound. It is an ionic compound. Polar can also be used to describe if something will dissolve in a polar solvent like water. NaHCO3 is a soluble ionic compound, so it would be considered polar in this case.

The species as a whole can be an ion, and yet not have net polarity on its bonds. Sulfate is tetrahedral, so each individual dipole vector would be opposed and cancelled, making the overall molecule non-polar (in the same way that this answer about CO2 details).

['Non polar molecules are symmetric with no unshared electrons.', 'Polar molecules are asymmetric, either containing lone pairs of electrons on a central atom or having atoms with different electronegativities bonded.']

Water, H2O, is a polar molecule. ... Hexane has an fairly equal charge distribution, meaning it is non-polar. Nothing about the water and hexane molecules attract each other. Therefore hexane is not soluble in water.

For example, ionic compounds, which are very polar, are often soluble in the polar solvent water. Nonpolar substances are likely to dissolve in nonpolar solvents. For example, nonpolar molecular substances are likely to dissolve in hexane, a common nonpolar solvent.
