I had been looking recently a lot of people asking about differences between the two, so this tutorial will definitely help the user

\(\Huge\color{red}{IONIC~vs~COVALENT~BOND} \) \(\Large\color{blue}{IONIC} \) 1)Formed by transference of electrons from electropositive (metal) to electronegative (non-metals) atoms. 2) Consists of electrostatic force between atoms. 3)Non-rigit and non-directional, does not cause isomerism (If you don't know isomerism don't worry just ask me or I will upload a tutorial) 4)It is a weak bond, since the electrostatic force between the ions can easily be broken. 5)It is polar in nature.

\(\Large\color{blue}{COVALENT BOND} \) 1) formed by sharing of electrons between two non-metal atoms when the electrons are equally contributed by the atoms. 2)Consists of shared pair of electrons which are attracted by both nuclei. 3)Rigid and directional, causes space isomerism and structural isomerism. 4)It is strong bond, since the paired electrons cannot be seperated easily. 5) it is non polar if the electronegativity difference is zero or small.

\(\Large\color{red}{Comparison~b/w~Ionic~Covalent~Compounds} \) \(\Large\color{blue}{Ionic} \) 1) Crystalline solids at room temperature. 2) high meltiing and boiling points. 3) Hard and Brittle 4)Freely soluble in water and in polar solvents. Insoluble in non- polar solvents. 5)In solid state bad conductors of electricity. Good conductors in molten state and in solutions. 6) Undergo ionic reactions. Rates of reactions are very high. Reactions are fast and instantaneous. \(\Large\color{blue}{Covalent~Compound} \) 1)Gases, liquids or soft solids under ordinary conditions. 2)Low melting and boiling points with the exception of giant molecules 3)Soft and waxy with the exception of giant molecules. 4) Usually insoluble in water and in polar solvents. 5)Bad conductors of electricity with few exceptions. 6)Undergo molecular reactions,rate of reactions are low.

see, you must be thinking that ionic bonds are weak and also hard, whats this! Ionic bonds within a salt crystal may be quite strong. However, if the crystal of salt is dissolved in water, each of the individual ions becomes surrounded by water molecules, which inhibit oppositely charged ions from approaching one another closely enough to form ionic bonds. Since cells are composed primarily of water, bonds between free ions are of little importance. So, within an aqueous environment, the interaction between ions of opposite charge is minimal and ionic bonds can be considered weak.

I posted this question in "Concepts and definition", Later on got to know its under thermodynamics, Oops. But still you can learn something from this tutorial Happy Learning !

Great job! 3)Non-rigit and non-directional, does not cause isomerism (If you don't know isomerism don't worry just ask me or I will upload a tutorial) I would like to know the explanation behind this myself. Ionic is weak? To me I get confused by that because we're taught that the electrostatic attraction is one of the strongest attractions there is. what makes the bond itself weak? is it the fact that electrons are transferred from the non metal to the metal?

Ionic bonds are weak compared to Covalent, (That is what i am saying) .and ya read the last para(important) Ionic bonds within a salt crystal may be quite strong. However, if the crystal of salt is dissolved in water, each of the individual ions becomes surrounded by water molecules, which inhibit oppositely charged ions from approaching one another closely enough to form ionic bonds. Since cells are composed primarily of water, bonds between free ions are of little importance.

Compounds having same molecular formula but different structure with different chemical and physical properties are called isomers. The phenomenon is called isomerism. So, as per the definition I don't think NaCl has many structures so, ionic... does not show isomerism. Got it? @Photon336 But ya... nice questions......

@Photon336 if you have doubt, we can discuss.... I also may not know somethings, we will work out together. I will reply you tomorrow..... I will be doing some physics now... take care....

Thanks so much for the explanation(s) absolutely

these lists are good for beginners, because you will notice that many molecules and compounds in nature are a combination of both.
