a. What two amides are obtained from the reaction of acetyl chloride with an equivalent of ethylamine and an equivalent of propylamine? b. Why is only one amide obtained from the reaction of acetyl chloride with an equivalent of ethylamine and an equivalent of triethylamine?
Topic: HESS'S LAW Hess's Law shows the changes in enthalpy. Annotation: ∆H Enthalpy is a state function, so when trying to calculate enthalpy, the final and initial standard conditions are important. There are three main rules to Hess's Law. 1. ∆H is proportional to reactants. Most known as the rule of multiplication. Multiply the ∆H rxn. 2. For reverse reactions, the sign for ∆H rxn pposite. 3. The state of matter for the reactants and products are important a. E.g. (aq), (l), (g), (s) Examples for Hess's Law Topic: Spontaneity/Driving Forces Definition Spontaneous: under certain conditions, a reaction occurs Nonspontaneous: under certain conditions, a reaction do
