why graphite is smooth?

Simple Answer (Bookish) : Within the layer, the carbon atoms are held by the strong covalent bonds but between the layers we have the weak Van der Waals forces and it therefore becomes easy for two layers to slip past each other giving Graphite its smooth nature and usefulness in lubrication.

In the case of water molecules, two atoms of hydrogen combine with one atom of oxygen to form a water molecule. In it, the 2 hydrogen donates 2 electrons (1 form each) to oxygen. Thus the oxygen attains octet whereas the hydrogen attains duplet
