School: University of Massachusetts Amherst (UMass Amherst )
-
From: GradeBuddy Pages: 7This lecture reviewed the different types of reactions that alkenes can undergo, which was discussed in the lecture before spring break.
-
From: GradeBuddy Pages: 7This lecture discussed, halogenation, hydration, oxymercuration/demercuration, and hydroboration of alkenes.
-
From: GradeBuddy Pages: 2This lecture reviewed Markovnikov's rule and the Hammond Postulate and how they contribute to the stability of carbocations. Additionally, addition with substituted cyclohexenes was discussed.
-
From: GradeBuddy Pages: 2This lecture reviewed stability in alkenes, and continued to discuss substitution. Carbocation intermediates and their properties were introduced.
-
From: GradeBuddy Pages: 3This lecture covered alkene naming, cis and trans isomers, and stability
-
From: GradeBuddy Pages: 3This lecture continued with electrophiles and nucleophiles, and introduced unsaturation of hydrocarbons as well as how to name alkenes.
-
From: GradeBuddy Pages: 3This lecture discussed endothermic and exothermic progress of reaction graphs and introduced radicals and polar reactions.
-
From: GradeBuddy Pages: 3This was the first lecture covering new material after exam 1. It introduced the different types of organic reactions, entropy, enthalpy, and the equations associated with them
-
From: GradeBuddy Pages: 2This lecture reviewed how to covert from 2D to 3D depictions of structures, the definition of enantiomers and chiral centers, as well as mesocompounds
-
From: GradeBuddy Pages: 11This review sheet covers material discussed in lectures 1-12
-
From: GradeBuddy Pages: 2This section reviewed chirality and enantiomers, and also discussed naming enantiomers. Additonally chiral centers and diastereomers were introduced
-
From: GradeBuddy Pages: 3This lecture reviewed chair flips and interactions that determine cyclohexane conformations, introduced disubstituted cyclohexanes and polycyclic molecules as well as began chapter 5 material on stereochemistry
-
From: GradeBuddy Pages: 2This lecture continued to cover cyclohexane conformations and introduced the idea of a ring flip
-
From: GradeBuddy Pages: 3This lecture covered the differences between stereoisomers and constitutional isomers, introduced ring strain, and covered characteristics of cycloalkanes, especially cyclohexane
-
From: GradeBuddy Pages: 3In this lecture, newman projections were discussed more in depth and cycloalkanes and their naming process and characteristics were also discussed.
-
From: GradeBuddy Pages: 4This lecture reviewed the characteristics of alkanes and functional groups, and discussed the process of how to name branched alkanes
-
From: GradeBuddy Pages: 4This lecture discussed the different types of non covalent interactions between atoms, as well as introduced alkanes and functional groups. Lewis acids and bases were also discussed.
-
From: GradeBuddy Pages: 2This lecture covered everything that has been covered already in the class, starting with orbitals and ending with acids and bases.
-
From: GradeBuddy Pages: 4This lecture recapped electronegativity and how it affects bonding, as well as dipoles. New material covered how to calculate formal charge on individual atoms, resonance structures, and introduced Bronsted-Lowry acids and bases
-
From: GradeBuddy Pages: 2Hybrid orbitals is recapped from the previous lecture. Electronegativity is then introduced, and how it affects what type of bonds are made between atoms. Dipole moments of molecules is also discussed.
-
From: GradeBuddy Pages: 5Atomic bonding is discussed in this lecture, which includes structural representation of bonds, the valence bond theory, and bond trends. Hybrid orbitals of electrons is then discussed
-
From: GradeBuddy Pages: 4A general description of course expectations, grading, required materials, etc., followed by an introduction to electron configurations and energy levels of electrons.
