dipole dipole

will someone please explain to me dipole dipole bonding and polarity for dummies, like as if u were explaining to an alien... i am confusion.

If I remember correctly,

So basically... One atom is able to attract the electrons in a covalent bond better than the other atom in the bond can. Since it can attract the electrons better, it has a greater share of the electrons. Electrons are negative, so this makes the atom's end of the covalent bond slightly negative. Since the other atom has a lesser share of the electrons, it is less negative and so it is slightly positive. Negative things and positive things attract, and so the slightly negative end (dipole) of one molecule is attracted to the slightly positive end (dipole) of another molecule, which is what dipole dipole attraction is

this is such a good explanation thank you! wishing u were my chem teacher

just another q- i hope this isnt too much to ask.. for questions asking which types of bonds are present, how do you approach? i know vdw is present in all, but can some molecules only have van der waals?

Okay, here is an explanation for dummies: a dipole means that there is a positive and a negative charge. As they are different, they have a polarity. This polarity forms the bonding.

A dipole dipole bonding means that there are alternating charges to form a bonding: positive-negative-positive-negative-... etc.

Example: a water molecule has both a positive (hydrogen) and two negative charges (oxygen). Many water molecules are connected by alternating charges, so hydrogen and oxygen atoms. These connections are the hydrogen bridge bonding.

You will have a polar bond when the difference in electronegativities is high enough. If you look at the values on the Pauling scale, a difference from around 0.1-1.8 will give you a polar covalent bond. If in the molecule, they are symmetrical (so balance out), there will be no overall dipole, as neither end is more negative or positive. If the polar covalent bonds are uneven in the molecule, then you will probably end up with a dipole-dipole.
You get hydrogen bonding when the H is bonded to a very electronegative element, like F, O or N
