The mechanism of esterification in presence of acid catalyst (H 2 SO 4 ) is proposed as follows Which of the following potential energy Vs reaction co-ordinate diagram is consistent with given mechanism ?

Correct answer

0

Step-by-step solution

Consider the reaction in forward direction k 1 fast E a 1 - low k 2 slow E a 2 - high k 3 fast E a 3 - low k 4 fast E a 4 - low k 5 fast E a 5 - low E a 2 is highest other choices do not fulful this requirement. Also esterification reaction Δ E ≈ 0 not much energy changes.
