What bond is more polar C-N or Br-S and which way does the dipole point?

The C-N bond is more polar than the Br-S bond based on differences in electronegativity values (∆EN). The dipole will have the negative pole at the N and the positive pole at the C. For Br-S, the negative pole is the Br and the positive pole is the S.

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
What is a bond between polar covalent molecules called?
A bond between two or more polar covalent molecules is called a Dipole-Dipole attraction (or interaction).
What element is a polar covalent bond?
No single element can form a bond. Only 2 or more elements can form bonds. Polar bonds occur when there is a dipole moment, or there is asymmetry in the structure. For example, HF forms a polar covalent bond.
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.
Is methanol more polar than acetone?
Methanol is more polar because is capable of dipole-dipole interactions AND hydrogen bonding while acetone is capable of just dipole-dipole interaction.
What is difference between ionic bond and polar bond?
In an ionic bond the lectrons are transfwrred and NOT shared. The bond is electrostatic in nature. In a polar covalent bond the electrons are shared, the more electronegative element attracts the shared electrons creating a build up of charge which forms a bond dipole.
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
Where does the dipole in the nitrogen-hydrogen bond point?
The dipole in the nitrogen-hydrogen bond points towards the nitrogen end. The arrow showing a dipole moment points towards the more electron rich region, with its tail at the electron poor region.
What determines the strength of a dipole - dipole force?
The more polar the molecule, the stronger the force.
Is the boiling point of 1-chloropropane higher than 1-bromopropane?
chlorine is more electronegative than bromine, so the C-Cl bond is more polar than the C-Br bond. Therefore, the permanent dipole - permanent dipole bonds are stronger between 1-chloropropane molecules, do more energy is required to break these intermolecular bonds, so the boiling point of 1-chloropropane is higher than 1-bromopropane.
What kinds of molecules do water dissolve?
It dissolves all kinds of molecules. However, the ones that it dissoves well are molecules that it can hydrogen bond with or molecules that are polar that it can have dipole-dipole interactions with.
What determines the the strength of a dipole-dipole force?
The more polar the molecule, the stronger the force.
