Which substance probably has the higher boiling point compound which is strongly polar or compound which is nonpolar?
Strongly polar. It's all about the intermolecular forces. A polar molecule is polar because of the electronegativity differences between the atoms. It results in something called hydrogen bonding, which is extremely powerful. It takes more energy to break stronger bonds...that's why you need hotter temperatures in order to melt polar substances.
Nonpolar substances have an electronegativity difference of 0. The only thing holding those substances together are London dispersion forces, which is a random force and the weakest of all the intermolecular forces. It's easier to break these bonds, that's why they have lower boiling points.

Is dihydrocapsaicin polar?
Dihydrocapsaicin is not very polar, demonstrated by the fact that it is only sparingly soluble in water.There are some polar groups in it but the benzyl-and methylnonanyl-groups are more strongly nonpolarPolar is bolded, nonpolar is italicalized:N-(4-Hydroxy-3-methoxybenzyl)-8-methylnonanamide
Is oxygen polar molecule or non polar molecule?
Definitely nonpolar.A molecule becomes polar if one of the atoms pulls electrons more strongly than another. But O2 is completely symmetrical--it's just two O atoms that are exactly alike. One can't pull more strongly than another, so it must be nonpolar.
Is the compound HCl is acid or base?
Strongly acidic
Is ketchup a neutral substance?
Ketchup is not considered to be a neutral substance. Ketchup is considered to be an acidic substance with a low pH.
If a particular compound has a Rf value of 0.95 is it strongly held on the paper or in the solution?
A compound with a high Rf value (close to 1) is strongly held on the paper and moves a short distance on the chromatography plate. This means it interacts more with the stationary phase (paper) than the mobile phase (solvent) and has low solubility in the solvent.

How the polarity of a compound will affect on both normal phase and reverse phase mode chromatography?
In normal phase chromatography, polar compounds are retained more strongly due to interactions with the polar stationary phase, while nonpolar compounds elute first. In reverse phase chromatography, the opposite is true: polar compounds elute first because they have less interaction with the nonpolar stationary phase, while nonpolar compounds are retained more strongly.
3 The label on a bottle indicates that the substance inside has a pH of 13 This tells you that the substance is A neutral B strongly acidic C mildly basic D strongly basic?
The substance with a pH of 13 is strongly basic. Substances with pH values greater than 7 are considered basic, and the higher the pH value, the stronger the basic nature of the substance.
Is oxygen polar molecule or non polar molecule?
Definitely nonpolar.A molecule becomes polar if one of the atoms pulls electrons more strongly than another. But O2 is completely symmetrical--it's just two O atoms that are exactly alike. One can't pull more strongly than another, so it must be nonpolar.
If oxygen which has an electronegativity of 3.5 bonds with hydrogen which has an electronegativity of 2.1 the bond between the two atoms will be classified as what polar bond?
The bond between oxygen and hydrogen is considered polar because of the difference in electronegativity between the two atoms. Oxygen, being more electronegative, will attract the shared electrons more strongly, creating a partial negative charge on the oxygen atom and a partial positive charge on the hydrogen atom.
Do polar and nonpolar molecules interact?
In general, polar molecules interact more strongly with other polar molecules (due to dipole-dipole interactions) and nonpolar molecules interact more with other nonpolar molecules (via London dispersion forces). However, there can be exceptions depending on the specific molecules involved and the conditions of the interaction.
Is the compound HCl is acid or base?
Strongly acidic
Do water molecules attract nonpolar molecules such as oil?
Yes, but they attract polar molecules more strongly."Hydrophobic" molecules is a misnomer. The nonpolar molecules in question are attracted to water molecules (usually more strongly than they're attracted to each other, even), but they get "shoved out of the way" by polar "hydrophilic" molecules which are even more strongly attracted to water molecules.
Why is anhydrous magnesium chloride insoluble in organic solvents?
Anhydrous magnesium chloride is insoluble in organic solvents because it is a highly ionic compound that is held together by strong ionic bonds. Organic solvents are nonpolar in nature and cannot effectively break these ionic bonds to dissolve the compound. Additionally, the high charge density of magnesium ions makes them strongly attracted to water molecules, further decreasing their solubility in organic solvents.
Does nonpolar means hydrophobic or hydrophilic?
Nonpolar molecules are typically hydrophobic, meaning they do not mix well with water. This is because water is a polar molecule and tends to interact more strongly with other polar molecules. Hydrophobic molecules generally prefer to interact with each other instead of with water.
Is it true that particles of a compound are most strongly held together when it is the state of a gas?
No. The particles are held strongly in the case of solid and least in the case of gases.
