Question

How can two molecules with the same chemical formula react differently?

Answer 1

"Different substances sometimes have the same chemical formula, such as glucose and fructose, but they have different components so they act differently."

Answer 2

The molecules that have the different structural formula but the same chemical formula are known as isomers. Isomers explain the relationship between molecular arrangements that, although differing in chemical or physical properties. Chemical reactions in which one isomer is transformed into different are called isomerizations. A rapid equilibrium that cannot be easily isolated involved by isomerization is known as tautomerization.
