Question

5) Which of the following correctly describes intermediates and transition states?

Answer(s): _________

a. An intermediate is always higher in energy than the substrate from which it came.

b. Both transition states and intermediates occur at minima on reaction coordinate diagrams.

c. Transition states have partially formed bonds whereas intermediates have fully formed bonds.

d. Transition states occur at maxima on reaction coordinate diagrams.

e. Both A and C

f. None of the choices.

I know for sure C is correct and also think A and D are also correct. Please explain why it is correct or why not. Thank you

Option A is incorrect as the intermediate is more stable than the substrate so on the energy diagram substrate will have higher energy

option C is correct option D is also correct as the transition state occupies a maxima in the reaction coordinate diagram
