Ionic forces are electrostatic forces and are very strong forces of attraction.
Ionic bonds create stronger intermolecular attraction than covalent bonds do; that is why rocks are harder than plastic.
Organic compounds exist as discrete molecules with much weaker inter molecular forces than those seen in ionic compounds?
In the liquid the intermolecular forces between covalent molecules are weaker than the forces between ions.
Well, a crystal is solid. If you mean, are ionic bonds stronger than covalent bonds, then the answer would be almost always. With a few exceptions, the ionic bond has a greater intermolecular force than a covalent bond. One exception might be a diamond and a weak ionic compound like RbBr.
Glycerol have hydrogen bonds,but this intermolecular forces are slightly weaker than in water
Covalent bonds are weaker. They simply share an electron making them sort of stick together. Ionic bonding works by energy transfer and then sticking together electromagnetically.
stronger
Ionic bonds require relatively high energies to be broken compared to the weaker hydrogen bond and van der Waals forces. Ionic compounds will thus have higher melting points than polar and organic compounds of similar molecular weight.
Actually, ionic bonds are generally much stronger than covalent bonds; except in solution.
Covalent solids generally have lower melting points than ionic solids. This is because covalent solids are made up of discrete molecules held together by relatively weak intermolecular forces, whereas ionic solids are made up of ions held together by strong electrostatic forces. The weaker intermolecular forces in covalent solids require less energy to overcome, resulting in a lower melting point.
A hydrogen bond is classified as a weak bond. It is stronger than van der Waals forces but significantly weaker than ionic bonds and covalent bonds. Hydrogen bonds can be found on deoxyribonucleic acid (DNA) where they bind the double helix structure of bases together.
If the shape of the meniscus is concave up then the cohesive forces are weaker than the adhesive forces. If the shape of the menicus is concave down then the adhesive forces are weaker than the cohesive forces. So capillary rise is where adhesive forces are stronger.
