Hint: To solve this we must know what happens in a synthesis reaction. Recall all the reactions you have learned to find out what happens in a synthesis reaction.A reaction of an acid and a base is known as the neutralization reaction. In a neutralization reaction, acid and base react to form salt and water.
Complete step by step solution: We are asked what happens in a synthesis reaction. Synthesis reaction is also known as direct combination reaction.
The word ‘synthesis’ indicates that in the reaction a product is synthesised or formed.
Synthesis reaction is a reaction in which two or more simple substances combine to form a complex product.
The reactants of a synthesis reaction can be elements or compounds but the products are always a compound.
The general form of a synthesis reaction is as follows:
An example of synthesis reaction is the reaction of sodium and chlorine in which sodium and chlorine combine to produce sodium chloride .
Thus, we can conclude that a synthesis reaction is a reaction in which two or more substances combine to form a new compound.
Thus, the correct option is (A) a reaction in which two or more substances combine to form a new compound.
Note: The reaction opposite to synthesis reaction is a decomposition reaction. In a decomposition reaction, one complex reactant breaks down to two or more simple products.A reaction in which two or more compounds combine to form a new compound is known as combination reaction.
