Draw and label a diagram showing the structure of water molecules to show their polarity and hydrogen bond f?

you can really draw a structure on here but it will be something like this

H-O-H above the O atom put 4 dots showing 2 pairs of non bonded electrons these electrons actually push or repel the 2 H atoms so the molecule is actually bent sort of like a triangle with no bottom like this /\  The O will have a negative charge and the H will have a + charge. You should put a small delta sign before it, it looks a bit like an S

When you want to show hydrogen bonds between the molecules of H2O remember that for hydrogen bonding to occur you must have a hydrogen atom attached to an electronegative atom bonding with another electronegative atom. So if you have 2 water molecules the hydrogen of one will join to the oxygen of the other. You show hydrogen bonds as a series of lines not a single line so something like this

H-O-H IIIIIIII O

single bond  -
hydrogen bond IIIIIIII

Hope that helps

Here you are, a photo of the water molecule structure in our blog, hope this helps!
