Question

A complex organic reaction mechanism involves the sequential formation of exactly 3 distinct reaction intermediates before reaching the final product. How many transition states will be present in the reaction coordinate diagram for this overall process?

Answer: 4

💡 Solution & Explanation

A sequential reaction pathway forms an alternating series of transition states and intermediates. The pattern is $Reactant \rightarrow TS_1 \rightarrow Int_1 \rightarrow TS_2 \rightarrow Int_2 \rightarrow TS_3 \rightarrow Int_3 \rightarrow TS_4 \rightarrow Product$. The number of transition states is always one greater than the number of intermediates.
