Are the attractive forces between polyethylene chains due to permanent dipoles or induced dipoles?
The attractive forces between chains are due to instantaneous induced dipoles, London dispersion forces,( not induced diipoles due to permananent dipoles). Polyethylene chains are long and the number of electrons is large- the intermolecular attraction will be significant.
What are dipoles?
Dipoles means "two poles". This refers to molecules or anything where the ends have different charges or fields or polarities. A dipole magnet has a north and south pole. Dipole failure in insulation is where + and - charged pieces oscillate and cause the insulation to fail. Many molecules are dipoles.
Are dipoles in magnets?
Yes! They are the ones doing the push(repel) and pull(attract). and even a single pole has no existence.this dipoles are resposible for dipole moment in a magnet.
What is a kooman antenna?
A vertical array of horizontal full-wave dipoles that are driven by transposed two-conductor line and backed with a parasitic reflecting curtain or horizontal dipoles.
What causes dipoles attractions?
The attraction between polar molecules.
What is the nature of attractive force among molecules in liquid bromine?
London dispersion forces the attraction OS instantaneous dipoles and included dipoles so you should select both A and C
How might a molecule with two strong bond dipoles have no molecular 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 a yagi?
A yagi is a directional antenna consisting of two or more dipoles.
What is the future tense of arise?
Will arise (for example, I will arise).
Is ClF4- polar or non polar?
There are two allowed structures of SF4Cl2... the cisform where one chlorine is in an equitorial position and one is axial, and the trans form where both chlorines are in axial positions. In the trans form the S-F bond dipoles all cancel each other, as do the S-Cl bond dipoles, because they are opposite each other. Therefore the molecule is non-polar. In the cisform, two of the S-F bond dipoles cancel, but because the other S-F bond dipoles are across from S-Cl bond dipoles, they do not cancel (S-F is more polar than an S-Cl bond). Therefore, the cisform is polar.
What substances are held together in the condensed state only by induced dipoles?
water
