KnowledgeBoat · Accepted Answer

(i) Difference between ionisation and electrolytic dissociation: Ionisation | Electrolytic dissociation -----------|--------------------------- Formation of positively or negatively charged ions from molecules which are not initially in the ionic state. |Separation of ions which are already present in an ionic compound Polar covalent compounds show ionization e.g., HCl, H₂CO₃, NH₄OH etc.,
| Electrovalent compounds show dissociation e.g., potassium chloride, lead bromide, etc.
KCl K⁺ + Cl^{-^{(ii) Difference between ionisation potential and electron affinity : Ionisation potential | Electron affinity ---------------------|---------------------- Ionization Potential is the amount of energy required to remove an electron from the outer most shell of an isolated gaseous atom.| Electron affinity is the amount of energy released when an atom in the gaseous state accepts an electron to form an anion. It is endothermic reaction.| It is an exothermic reaction. (iii) Difference between polar and non-polar molecule : Polar molecule | Non-polar molecule ------|-------------------- In a polar molecule, shared pair of electrons are unequally distributed between the two atoms. | In a non-polar molecule, shared pair of electrons are equally distributed between the two atoms. In polar molecule, the atom which attracts electrons more strongly develops a slight negative charge while the other develops a slight positive charge. | The non-polar molecule is symmetrical and electrically neutral. (iv) Difference between normal salt and acidic salt : Normal salt | Acidic salt ------------|-------------- The salt formed by complete replacement of the replaceable hydrogen ion of an acid molecule by a basic radical [metallic or ammonium ion]| The salt formed by partial replacement of the replaceable hydrogen ion of an acid molecule by a basic radical [metallic or ammonium ion]. For example,
2NaOH + H₂SO₄ Na₂SO₄ + 2H₂O
2NaOH + H₂SO₃ Na₂SO₃ + 2H₂O
[Both H ions in sulphuric and sulphurous acid are replaced by metallic radical sodium. ] | For example,
NaOH + H₂SO₄ NaHSO₄ + H₂O
NaOH + H₂SO₃ NaHSO₃ + H₂O
[Only one H ion in sulphuric and sulphurous acid is replaced by metallic radical sodium. ] (v) Difference between saturated hydrocarbons and unsaturated hydrocarbons : Saturated Hydrocarbons | Unsaturated Hydrocarbons -----------------------|-------------------------- All the four valencies of each carbon atom are satisfied by forming single covalent bonds with carbon and with hydrogen atoms. | The valencies of at least two carbon atoms are not fully satisfied by the hydrogen atoms. They are less reactive due to the non-availability of electrons in the single covalent bonds, and therefore they undergo substitution reaction.|They are more reactive due to the presence of electrons in the double or the triple bond, and therefore undergo addition reaction.}}
