ionic bond, covalent bond ,hydrogen bond , coordination bond- order of strength ? plz tell the order of difficulty in breaking them & explain the following- na2co3.10h2o on heating gives na2co3.h2o + 9h20. on further heating we get anhydrous na2co3. why? how the water molecules are bonded in na2co3.10h2o. saumya

Covalent bondsare formed between atoms which have- Unsatisfied valency- No inert gas electronic configuration- These are directional bonds- formed by sharing of electronsIntermolecular forces- Much weaker than covalent bond- These are not directional (except Hydrogen bonds)- These are more electrostatic in nature- exist between stable molecules- can be Hydrogen bonding, dipole-dipole and induced dipole-induced dipole (london dispersion).covalent > ionic > metallic > h-bonds > dipole-dipole > dispersionFrom strongest to weakest:Now the answer of to your question:1.Covalent bonding (bonding that happends by the sharing of electrons).2.Ionic-bonding (most commonly found in salts, it forms by the losing and gaining electrons ** electrons are not shared in this type of bonding).3.Metallic bonding (between metals only).4.H-bonding (this type of bonding tends to form with Nitrogen, Oxigen and FLuorine)5.Dipole-Dipole(forc e that exist because of the interaction of dipoles on polar molecules in close contact).6.London Dispersion (simultaneously Dipole-dipole moments)Thank YouRuchiAskiitians Faculty
