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
Why does methylbenzene have higder boiling point than benzene?
It is a bigger molecule and so the van der Waals dispersion forces will be bigger. Methylbenzene also has a small permanent dipole, so there will be dipole-dipole attractions as well as dispersion forces. The dipole is due to the CH3 group's tendency to "push" electrons away from itself. This also affects the reactivity of methylbenzene Chemguide
Why can dipole moment be determined only for neutral system of charges not for charged one?
The very definition of dipole is that two equal oppositely charges separated by a very very small distance. Hence + and - would cancel and hence neutral
What is the water cycle in a short term?
the water vapor takes a short time
How do van der Wals forces hold molecules together?
When molecules are close together, a slight attraction can develop between the oppositely charged regions of nearby molecules. Apex------They form temporary, weak dipole attractions between molecules.
What is the major attractive force in CO?
Dipole dipole (CO has a small dipole moment) and London dispersion forces.
Why is HCN is a dipole-dipole compound?
HCN is a linear molecule and as nitrogen is the most electronegative atom a small negative charge builds on the nitrogen atom and a small positive charge on the hydrogen. This forms a dipole (dipole means two oppositely charged ends). The intermolecular forces between HCN molecules are electrostatic and are caused by the dipole on one molecule interacting with one on another molecule. This is called dipole -dipole interaction.
What does a dipole look like in a molecule?
A dipole is a as small piece having separate and opposite electrical charges at the ends.
Is NF3 polar nonpolar or ionic?
Nitrogen trifluoride ia a polar compound, with a small dipole moment of 0.234 debye. F has a higher electrnegativity than N , with a 0.94 difference. The lone pair will also cause a small dipole in the opposite direction to the polar bonds. This accounts for the small net dipole moment
What molecule possesses a net dipole moment?
Typically one where bond dipoles do not cancel due to the molecular symmetry. The lone pairs also give rise to a small dipole moment and these may cancel out small bond dipoles it depends on the relative directions of the dipole moments.
Does the SF6 anion have a dipole moment?
The neutral SF6 molecule has no dipole moment. The gas phase SF6- ion is not that well understood- on the basis that the shape is distorted octahedral a small dipole would be expected.
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
Is N2 have a dipole moment?
N2 is a completely symmetrical molecule, therefore it has no dipole moment.

What is dipole movement?
The correct spelling is dipole moment instead of dipole movement. The definition of dipole moment is the net molecular polarity measure. It is the separation of dipole ends and the magnitude of charges.
What is the relationship between a polarity and hydrogen bond?
Polar molecules have a dipole moment and they have intermolecular forces that include dipole-dipole interaction. A hydrogen bond is the attraction between a hydrogen bonded to N, O, F atom with N, O, F lone pair. Small molecules that exhibit this effect are HF, H2O and NH3. The example molecules are all polar. The hydrogen bond interaction is stronger than a normal dipole-dipole interaction.
Do you want the gross expense ratio to be small or large when investing?
i will definitely need it to be as small as possible since it will determine actual amount of net expenses i must pay.also in the short term i might not have enough cash for such expenses
