Question 26

A redox reaction involves the transfer of electrons from one atom to another.

In a redox reaction, oxidation and reduction processes occur, where one atom or molecule loses electrons (oxidation) and another gains them (reduction).

A) combustion reaction

A combustion reaction is a chemical reaction that typically involves a fuel reacting with oxygen to produce heat and light, usually resulting in carbon dioxide and water. This type of reaction does not specifically involve the transfer of electrons between atoms.

B) synthesis reaction

A synthesis reaction involves two or more reactants combining to form a single product. While bonds are formed and broken in this process, it does not primarily focus on the transfer of electrons, distinguishing it from redox reactions.

C) redox reaction

A redox reaction, short for reduction-oxidation reaction, is characterized by the transfer of electrons between atoms. One species is oxidized by losing electrons, while another is reduced by gaining those electrons, making this the correct choice.

D) double-displacement reaction

A double-displacement reaction, also known as a metathesis reaction, involves the exchange of ions between two compounds, resulting in the formation of new compounds. This process does not involve the direct transfer of electrons as seen in redox reactions.

Conclusion

The correct answer, redox reaction, accurately describes the process of electron transfer between atoms, which is the core element of the question. Other options, such as combustion, synthesis, and double-displacement reactions, do not focus on electron transfer, thereby confirming their incorrectness in this context.
