Which of the following statements about molecules is true A

Which of the following statements about molecules is true?

A. The function of the molecule is independent of its structure.

B. Even a small change in the structure can affect the function of a molecule.

C. Molecules with the same number of atoms, can have different structures but they can still perform the same function.

D. As long as the molecules have the same functional groups, they are interchangeable.

E. A molecule can be functionally replaced by its mirror image.

Solution

A. The function of the molecule is independent of its structure. ----> TRUE

B. Even a small change in the structure can affect the function of a molecule. -----> TRUE

C. Molecules with the same number of atoms, can have different structures but they can still perform the same function. ----> FALSE (molecules with same atoms and different structures are known as isomers, which typically produce different effects)

D. As long as the molecules have the same functional groups, they are interchangeable. ----> FALSE (molecules with the same functional groups cannot be always interchangeable)

E. A molecule can be functionally replaced by its mirror image. ----> FALSE
