Dipoles

Question 1

Dipoles occur when

Answer 1

A dipole occurs when opposite ends of an atom, molecule or compound have different electrical charges

Question 2

When do induced dipoles occur?

Answer 2

Induced dipoles occur when one molecule with a permanent or temporary dipole repels another molecules electrons inducing a dip moment in that molecule

Question 3

When are temporary dipoles created

Answer 3

When electrons that are constantly moving around the nucleus, spontaneously come into close proximity. This uneven distribution of electrons can make one side of the atom more negatively charged than the other.

Question 4

PDPDA

Answer 4

This type of Vanderwall force occurs when permanent dipoles are present in molecules

Question 5

Why does permanent dipole occur?

Answer 5

It occurs when two atoms or a molecule have different electronegativities. One atom attract electrons more than the other becoming more negative while the other becomes more positive.
