Question

Which of the following represents a synthesis reaction?
A) AB + XY 	?AY + XB
B) AB + XY ? AY + XB
C) AB ? A + B
D) A + B ? AB

Accepted Answer

A synthesis reaction is a type of chemical reaction in which two or more simple substances combine to form a more complex product. The general form is A + B → AB, where A and B are the reactants that come together to form AB, a more complex molecule. This is exactly what is described in option D.
