Hello, good evening student.

So the question is saying explain the forces of attraction hydrogen bond between molecules of water in liquid water, right? and draw a picture of three four molecules of water and show the hydrogen bone between them.
00:14
Label the h bone, right? so let's see.
00:17
So the hydrogen bond in water is the hydrogen bone, sorry, the hydrogen bone, the h bone in water, the h bone in water.

Is a dynamic attraction between is a dynamic attraction between so i am writing between by b slash w so it's just abbreviation between neighboring water molecules neighboring water molecules involving one hydrogen atom involving one hydrogen atom located between two oxygen atoms located between two oxygen atoms and oxygen atom from another molecule.

Another molecule of right and now see let's see why hydrogen bonding arises so it arise because of high electronegativity of oxygen because of high electronegativity there is there is significant there is significant amount of en difference between in difference between hydrogen and oxygen now let's see let's see a diagram like how it happened okay so let's say this is our one hydrogen molecule this is another water molecule this is another water molecule right and this is another water molecule like okay now this oxygen is electronegative so this will have a negative charge here and this will have a positive charge similarly we will have a negative charge here we will have a positive charge here negative charge here and positive charge here negative charge here and positive charge here okay similarly we will have positive charge partial positive charge here is well now we can see so see this has a negative charge okay this has a positive charge so there is interaction between oxygen of one molecule and hydrogen of another molecule okay so here we have interaction also we can have interaction in this like this one and so just let me redraw this let me redraw this also we will have so let's say we we have a molecule here right, so there will be an interaction here...
