Alkane Formulas All C-C single bonds Saturated with hydrogens Ratio:H n2n+2 Alkane homologs:ch3(ch2)nCH3 Same ratio for branched alkanes

Classification Primary: carbon with -OH is bonded to one other carbon. Secondary: carbon with-OH is bonded to two other carbons. · Tertiary: carbon with-OH is bonded to three other carbons. Aromatic(phenol): -OH is bonded to a benzene ring

Introduction NMR is the most powerful tool available for organic structure determination. It is used to study a wide variety of nuclei:

1. Background Information 2 Structure 3. Language Point 4. Appreciation of the Text

The role of abstractions In this lecture, we are going to look at a very different style of creating large systems, a style called object oriented programming. This style focuses on breaking systems up in a different manner than those we have seen before To set the stage for this, we are first going to return to the notion of

Slide 14.4.1 Cleaning up some details of our implementation So we have seen a first pass at building an object-oriented tem, using Scheme as the base. There are a few details that The need for self-reference

Slide 15.6.1 The next stage in the evolution of our evaluator is to pull the 5. Environment as explicit parameter environment out as an explicit parameter. Up until now we could rely on just having a single environment in which to store (eva1'(pus*64)) bindings for variables. It made sense to have a global
