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
What type of molecule has Dipole-Dipole forces created?
Ay molecule with a net dipole moment will have dipole -dipole interactions. These are molecules with polar bonds caused by a diference in electronegativity between the atoms being bonded.
Is polar bond always polar molecule?
no not really if they dont have an acute bond angle between them or have a 180 degree bond angle with the polarities running in opposite direction the overall molecule will not have a dipole.
What do you mean by Dipole Moment and Induced Dipole Moment?
Induced dipole forces result when an ion or a dipole induces a dipole in an atom or a molecule with no dipole. These are weak forces. An ion-induced dipole attraction is a weak attraction that results when the approach of an ion induces a dipole in an atom or in a nonpolar molecule by disturbing the arrangement of electrons in the nonpolar species. A dipole-induced dipole attraction is a weak attraction that results when a polar molecule induces a dipole in an atom or in a nonpolar molecule by disturbing the arrangement of electrons in the nonpolar species.
What is the dipole moment for CCI4?
It is a symmetrical tetrahedral molecule so has zero dipole moment.
What are the conditions for ammonia molecule to be IR active?
An IR Active stretch simply means that the vibrations of the molecule result in an overall dipole of the molecule. If a stretch has a dipole, it is IR active. If a stretch does not have a dipole. then it is IR Inactive.
What molecule has an overall dipole moment?
All polar molecules have a permanent dipole moment, but London dispersion forces in non-polar molecules can cause temporary dipole moments as well.
What is molecular dipole moment?
The molecular dipole moment is a measure of the separation of positive and negative charges within a molecule. It is a vector quantity that indicates the overall polarity of a molecule. It is determined by the individual dipole moments of the bonds within the molecule and their spatial arrangement.
What determines whether a molcule has an overall dipole moment?
Generally if a molecule contains polar bonds and the bond dipole moments do not cancel each other out then that molecule will have an overall dipole moment. Bond dipoles arise when there is a significant difference in electronegativity between the atoms in the bond. There some cases such as phosphine PH3 where the lone pair can make a significant contribution to the molecular dipole moment.
How might a molecule with two strong bond dipoles have no molecule dipole at all?
A molecule with two strong bond dipoles can have no molecular dipole if the bond dipoles cancel each other out by pointing in exactly opposite directions. For example, in carbon dioxide (a linear molecule), the carbon-oxygen bonds have a large dipole moment. However, because one dipole points to the left and the other points to the right, the dipoles cancel and overall there is no molecular dipole.

What is the term for the overall direction of partial negative charge in a molecule having one or more dipoles?
Net dipole
Which molecule have permanent dipole moment?
Every polar molecule has a permanent dipole.
Why a dipole develops in a molecule?
a dipole develops in a molecule due to unequal sharing of electrons.

Is benzil a polar molecule?
It might be tempting to think Benzil is a polar molecule because of the C=O bonds, but the high level of symmetry in the molecule cancels out any overall dipole and leaves the molecule non-polar.
What are the example of dipole-dipole interaction?
the interaction between the hydrogen of one molecule and the partial negative atom of other molecule is called dipole dipole interaction
