Purpose of the Chapter

The purpose of the chapter is to highlight the increasing range of possibilities open to the chemist by including new techniques of electrochemical fluorination into his synthetic repertoire as a result of advances in the field over the past five to ten years. 

Without referring back, make a list of the most important items you learned in this chapter. What do you believe was the overall purpose of the chapter What if ... 

Again this chapter begins with a general statement - an assertion which the author invites the reader to accept on trust, as the setting for the exploration which is the purpose of the chapter to trace the emergence of two [new] concepts.. Here, then, the introduction tells us both what the writer will do in the chapter and how (through the case study). 

The purpose of the chapter is to describe the operative technique of cancellous bone harvesting from proximal tibia for filling the bone cavities in the orofacial region on the basis of literature review and own experience. The chapter includes step-by-step description of the operative technique, postoperative care and early rehabilitation. Possible complications at the donor site, such as fractures due to the weakening of the tibia, donor site morbidity, the necessary period of postoperative hospital stay and mean volume of cancellous bone obtained are also described. 

We have already described and analyzed all the financial mathematical tools needed for our calculations to fulfill the purpose of the chapter. Using these basic tools, we now introduce two concepts that are important for comparison and decision among alternatives (real-life situations and engineering projects). First, the net present value is one of the most common tools to economically evaluate projects. One of the limitations of NPV is when you are comparing two or more projects with different lifespans. Although this difficulty can be remedied, it could be cumbersome. Second, the annual equivalent benefits/costs has the advantage over NPV that you can compare projects with different lifespans. 

Here the reader is confronted with a practical problem that the current chapter addresses. Only after posing a clear-cut problem without an evident solution, will the student see the purpose of the chapter and how the material presented sheds light on the stated problem. 

The purpose of the chapters that follow is to summarize the results... 

The purpose of the chapter was quantum-chemical calculation of components of synthesis of acetyl chloride (HI) and 5-acetylojgrmethyl-2-chlorine-5-ethyl-l,2,3-dioxaphosphorynan (II) and a product l-[2-(o-acetylmethyl)-3-o-acetyl-2-ethyl]-methyldichlorinephosphite (I) by method AB INITIO in basis 6-3IIG, a theoretical estimation of their acid force and an establishment of dependence between acid force of components of synthesis pKa (HI) and pKa (II) and pKa (I). 

The purpose of the chapter dealing with equilibrium thermodynamics of the perfect solid (Chapter 4) is to elaborate, on the one hand, simple expressions for the thermodynamic functions of the chemical ground state and, on the other hand, to make the reader familiar with questions of internal and external equilibria, not least with the intention to provide the equipment to deal with the thermodynamics of defect formation. (The major portion of the free enthalpy at absolute zero consists of bonding energy, while the temperature dependence is largely determined by the vibration properties.)...
