What has a higher boiling point CH3CH3 or CH3Cl?
CH3Cl because it is polar meaning it has both a dipole-dipole bond and dispersion bond, where as CCl4 is non polar and only has a dispersion bond. Since CH3Cl is bonded together stronger, it will be harder to break up and therefore a greater temperature will be required to boil it Edited (9/20/10) CCl4 has a bp 76.7 C, CH3Cl has a bp -24.2 C, see wikipedia or MSDS info. That means the first answer is wrong. Boiling points are based on intermolecular forces. Stronger the forces, lower the vapor pressure, higher the bp. The reason CCl4 has a higher boiling point is because dispersion forces increase with increasing molecular weight and # of electrons. Therefore the greater number of electrons in CCl4 create a stronger dispersion force than the combined dipole+dispersion forces in the CH3Cl.
What compound is more polar and soluble in water methane or methanol and why?
Acetonitrile is slightly more polar than methanol. This is due to the presence of the C-N triple bond in acetonitrile (CH3CN).
Is sucrose an organic molecule?
AnswerYes.See the Related Questions link to the left for more information about how to determine if any molecule is polar or not.Yes, Sucrose is a polar molecule because the formula is C12H22O11 and any formula with a single Hydrogen molecule, or a single Oxygen molecule is polar. It is held together with dipole-dipole forces.
H3O plus is a polar or nonpolar molecule?
H2O is a polar molecule; +H3O is even more so.
A science word that starts with d?
This is more of a chemistry unit, but it can still be considered physics (maybe?) Anyway, dipole moment of molecules can be measured in Debyes. This is more of a chemistry unit, but it can still be considered physics (maybe?) Anyway, dipole moment of molecules can be measured in Debyes.
What determines the strength of dipole-dipole force?
dipole moments increase with the polarity
How is the difference between polar and non polar related to electronegative?
What creates dipole moments in polar molecules is dependent in the length of the bond, the size of the atoms, and the electronegativity of the atoms, for example the C-Cl bond is much more polar than the C-N bond because Cl is more electronegative. Do keep in mind though that if the molecule is symmetrical the dipole moments can cancel out to become 0. Hope this answers your question.
What is a bond between polar covalent molecules called?
A bond between polar covalent molecules is called a hydrogen bond. It is a weak type of bond that forms between a partially positive hydrogen atom and a partially negative atom (such as oxygen or nitrogen) in another molecule.
Is a dipole-dipole interaction more likely to occur in a polar or nonpolar molecule?
A dipole-dipole interaction is more likely to occur in a polar molecule rather than a nonpolar molecule.
What determines the strength of a dipole - dipole force?
The more polar the molecule, the stronger the force.
Which molecule has polar bond but its overall dipole momen is zero?
Symmetric molecules have no dipole moment. An example is carbon tetrachloride, CCl4 , which has no dipole moment yet the C-Cl bonds are polar, (chlorine is more electronegative than carbon). The chlorine atoms each have a small negative charge but because the molecule is tetrahedral there is no dipole and therefore no dipole moment
Boiling point of polar molecule?
The boiling point of a polar molecule is typically higher than that of a nonpolar molecule of similar size because polar molecules have stronger intermolecular forces, such as dipole-dipole interactions and hydrogen bonding, which require more energy to break. These stronger intermolecular forces result in a higher boiling point for polar molecules.
Is methanol more polar than acetone?
Yes, methanol is more polar than acetone because it has a higher dipole moment and stronger hydrogen bonding capabilities due to its hydroxyl group. Acetone is a less polar solvent compared to methanol.
What determines the the strength of a dipole-dipole force?
The more polar the molecule, the stronger the force.
Is a dipole polar or nonpolar?
A dipole is polar because it has a separation of charge, with one end being more positive and the other end more negative. This charge asymmetry gives rise to a net dipole moment, making the molecule polar.
How does elecronegativity affect the polarity of the bond between two atoms?
The more electronegative an atom is the more "pull" the atom will have on the electrons in the molecules. For example, water (H2O) contains the very electronegative atom Oxygen. Oxygen would pull more electrons toward it so the hydrogen would essentially lose their electrons. The dipole moment would point towards the oxygen. Therefore, the more electronegative an atom is the more the dipole moment will point in its direction therefore affecting polarity of the bond.
Which has more dipole moment C2H3CL or C2H5CL?
C2H5-CN ethyl cyanide has high dipole moment while C2H5-NC molecule is not possible due to incomplete valency of carbon atom.
