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 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
A covalent bond in which electrons are shared equally is called a what?
The only time that electrons will be shared equally is when the covalent bond is between two atoms of the same element. The reason for this is that electronegativities differ between each element, and if two elements with a covalent bond have different electronegativities then the electrons will be held more strongly by the element with the higher electronegativity.
Is azo dye and diazo compound same thingh?
Yes. They both contain -N=N- linkage and are strongly colored compounds.
Is NO nonpolar?
NO is polar. If you compare the electronegativities (how strongly the element pulls on electrons) N 3.04 O 3.44 ( bigger therefore pulls electrons harder) The electrons will be drawn to the oxygen causing it to be slightly negative, and the N to be slightly positive.
What is NaOH in science?
NaOH is the chemical symbol for the compound sodium hydroxide, which is a strongly alkaline substance also known as lye.
Particles in this substance interact very strongly with each other?
Depends what "this" substance is
What is a strongly irritating basic substance?
caustic
Is BeCl2 polar or nonpolar bonds?
Beryllium chloride is a strongly ionic compound, and it therefore polar by definition, since it consists of a beryllium cation and two chloride anions. It is therefore a salt, and will readily dissolve in water, which is also polar.
The molecules in compound AB are strongly polar while the molecules in compound XY are non-polar which substance probably has the higher boliling point?
AB, of course. Even the weak hydrogen bonding interaction between polar molecules can, when shared among many molecules, have a strong aggregate effect and resist the molecular jiggling apart that is the actual heat from applied energy.
Because the electrons in a molecule of hydrogen fluoride are more strongly pulled toward the fluorine atom is the molecule nonpolar?
yes
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.
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?
D
Is the compound HCl is acid or base?
Strongly acidic
The particles of a compound are most strongly held together when it is in the state of a?
solid
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.
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.
