Question: Permanent and Temporary Dipoles
Answer: Dipoles:
· A molecule with a positive end and a negative end
· When a molecule has a dipole it is called polarised
· There are several ways a molecule can become polarised
Permanent Dipoles:
· Permanent dipoles occur when a molecule has two atoms bonded together which have substantially different electro negatively, so that one atom attracts the shared electrons much more than the other
· Hydrogen chloride has a permanent dipole, because chlorine is much more electronegative than hydrogen, and so attracts the shared electrons more
· Molecules with a permanent dipole are called polar molecules
Instantaneous Dipoles:
· Some molecules do not possess a permanent dipole, because the atoms that are bonded together have the same, or very similar, electro negatively, so that t...(short extract)
