One of the most frequently asked exam questions in this chapter is:“What is the relationship between the following two molecules?”. We’re going to learn a systematic method to solve these questions. 1 concept Different atoms or different connectivity. ...
a. What is the value of n in Hückel's rule when a compound has nine pairs of p electrons? b. Is such a compound aromatic? Verified step by step guidance 1 Hückel's rule states that a compound is aromatic if it has (4n + 2) π electrons...
In addition, the amount of energy needed to start a reaction is the activation energy. This energy is required to form the transition state, which occurs when reactant molecules collide, and the rate constant, k, is related to temperature by the Arrhenius equation. Process Analytical ...
