Question

What kind of chemical reaction is synthesis? Choose the correct option(s) for its explanation:
This question has multiple correct options,
A. Complex products are formed.
B. Reactants are always elements.
C. Reactants are always compounds.
D. It is a type of combination reaction.

Answer 1

Hint: You will know how a synthesis reaction occurs, and what kind of products are being made. You can use the basic knowledge of different forms of reactions you have learned, such as the combination reaction, etc.

Complete step-by-step answer:
According to the question, we have asked what kind of chemical reaction synthesis. So, we should know what synthesis means, a Synthesis reaction, also referred to as a direct combination reaction, and is a sort of chemical reaction, in which a more complex product consists of two or more simple substances. The next reactants may be elements or compounds, but the products are still a compound.
 The general form of a synthesis reaction can be written as \[A + B \to AB\]
Therefore, from the description above, we may infer that the synthesis reaction is a combination reaction in which reactants can and may not even be elements or compounds and that the products that form often become a compound and products that form become complex.
Hence, options A and D are correct.

NOTE: The above definition of the chemical reaction can be described by rearranging, apart from physical alteration or nuclear reaction the molecular or ionic structure of a substance. Combination, decomposition, single replacement and double replacement reactions are forms of reactions.
