A reaction in which smaller molecules are bonded to form larger ones is called a:
A)composition reaction
B)synthesis reaction
C)thesis reaction
D)decomposition reaction

Question

Quizplus · Accepted Answer

Synthesis reaction is a chemical reaction in which two or more substances combine to form a single, more complex substance. This is also known as a composition reaction. Choice A (composition reaction) is also correct, but it is not the best choice as it is less commonly used. Choice C (thesis reaction) and D (decomposition reaction) are incorrect as they refer to different types of reactions. A decomposition reaction is the opposite of a synthesis reaction, where a complex substance is broken down into simpler ones. A thesis reaction does not exist in chemistry.
