1)The oxygen's high electronegativity cause the shared pair of electron move a little toward oxygen atom.So,oxygen atom is partial negative and hydrogen is partial positive.The adjacent hydrogen atom in water molecule attract the oxygen atom because of electrostatic.
2)The oxygen's high electronegativity cause the shared pair of electron and HYDROGEN'S ELECTRON CLOUD move a little toward oxygen atom.So,hydrogen atom is strong positive.The hydrogen atom attract the lone pair of adjacent hydrogen atom in water molecule.
The two process is the information about the formation of hydrogen bond in water molecule.
So,what is true?Or..both wrong?Who can explain the formation of hydrogen bond?
The electronegativity is the ability of atom to attract the bonded pair...but the oxygen's high electronegativity cause the shared pair of electron and electron cloud?....High Elelctrongativity alos cauise atom to attract the electron cloud????
and i have some question:
the hydrogen bond is a type of dipole-dipole movement.Someones say the dipole-dipole movement is not related to lone pair of electron.but,the number of lone pair is related to the number of hydrogen bond.So wrong about this?hydrogen is not a dipole-dipole movement?
How the number of lone pair affect the number of hydrogen bond in a molecule?
