GENERAL CHEMISTRY QUESTIONS
AND ANSWERS | LATEST UPDATE |
2024/2025 | GRADED A+
What is the difference between an ionic bond and a covalent bond in terms of electron transfer

and sharing?


✔✔ An ionic bond involves the transfer of electrons from one atom to another, creating

positively and negatively charged ions, whereas a covalent bond involves the sharing of electron

pairs between atoms.




How does the concept of atomic orbitals explain the bonding in molecules?


✔✔ Atomic orbitals describe the regions in an atom where electrons are likely to be found. The

overlap of atomic orbitals from different atoms forms bonds in molecules, such as sigma and pi

bonds.




What is the role of a solvent in a chemical reaction or solution?


✔✔ The solvent is the substance that dissolves the solute to form a solution, providing a medium

for the reaction or interaction to occur.

, How does the concept of electronegativity help predict the type of bond formed between two

atoms?


✔✔ Electronegativity measures an atom’s ability to attract and hold onto electrons. A large

difference in electronegativity between two atoms usually indicates an ionic bond, while a small

difference suggests a covalent bond.




What is the significance of the octet rule in chemical bonding?


✔✔ The octet rule states that atoms tend to bond in such a way that they achieve a full outer

shell of eight electrons, similar to the electron configuration of noble gases, leading to stable

compounds.




How do you determine the oxidation state of an element in a compound?


✔✔ The oxidation state of an element in a compound can be determined by assigning oxidation

numbers based on a set of rules, including the assumption that the sum of oxidation states equals

the charge of the compound.




What is the concept of chemical equilibrium and how is it represented in a chemical reaction?


✔✔ Chemical equilibrium occurs when the rates of the forward and reverse reactions are equal,

and the concentrations of reactants and products remain constant over time.
