Write an essay about molecular modelling, its uses, and applications, and use a freely available modelling software from the internet and include the details of the modelling you followed, and give examples of at least three models you developed. The paper must be at least 1500 words, double spaced, in standard fonts and contains at least two references. Please follow APA format.
Enamines are generally reactive toward electrophiles. For example, compound E reacts with HBr at room temperature. Surprisingly, enamine F is unreactive with HBr even at 150 °C. Provide a rationale forthis difference in reactivity.
