Chemistry Class 9 Chapter 4 Chemical Bonding Solved Question Answer from Sindh Board Exercise

We recommend our students to do smart work by remembering most repeated questions from the board examination.

Therefore, We have prepared notes from the most repeated questions of Chemistry Class 9 Chapter 4 Chemical Bonding Solved Question Answer from Sindh Board Exercise.

Here are the most repeated Questions with Answers prepared from the Class 9 Chemistry Sindh Textbook.

Q. What is a coordinate covalent bond? Explain it.

Ans. A coordinate covalent bond, also known as a dative bond, is a type of covalent bond where each atom contributes one electron, resulting in partial ionic characters.

Definition: Thus, we can define a coordinate covalent bond as: "The type of bond in which bond pair of electrons is contributed by one atom only is called coordinate covalent or dative covalent bond." Concept of donor and acceptor: A coordinate covalent bond is formed between an atom that donates an electron pair and another atom that accepts the electron pair, represented by an arrow.

Nature Of Coordinate Covalent Bond or Dative Covalent Bond: In actuality, there is no distinction between dative and conventional covalent bonds once they are created. The process of formation is the only distinction between the two. These chemicals' characteristics are comparable to covalent compounds because of their covalent bond formation.

Q. Explain the characteristics of Ionic Compounds.

Ans: Characteristics of Ionic Compounds: 

State: The oppositely charged ions are mutually surrounded by one another in ordered configurations within the crystals of ionic compounds. Therefore, at normal temperatures, ionic compounds are solid.

Melting And Boiling Points: Because of the strong electrovalent connections that occur between the ions, ionic compounds have extremely high melting and boiling temperatures.

Conductivity of Ionic Solids: ionic solids, do not conduct electricity as the ions are not free to move.

Conductivity Of Aqueous And Fused Ionic Compounds:

These substances exist as freely moving ions in an aqueous solution, which allows them to conduct electricity. Ions in a molten state can likewise travel freely in a similar manner. 

Solubility: logic In polar solvents, or solvents with a high dielectric constant like water, compounds are typically soluble. However, non-polar (organic) solvents with low dielectric constants, such as benzene, petrol, carbon tetrachloride, etc., are insoluble in ionic compounds.

Nature: They are mostly inorganic compounds.
