In Deciding What Constitutes Essential Organic Chemistry, We Have Kept In Mind What The Students Need To Know For Making Their Career In Medicine Or Other Health Professions. Based On The Answers To Those Questions, The Content Has Been Prepared And Organizational Choices With The Following Goals In Mind: ? Students Should Understand How And Why Organic Compounds React The Way They Do. ? Students Should Understand That The Reactions Require Basic Knowledge Which Is Incorporated In This Book. ? Students Should Appreciate The Fun And Challenge Involved In The Synthesis Of Organic Compounds. ? Students Should Analyze How The Organic Chemistry Is Integral To Biology, To Medicine And To Their Daily Lives. In Order To Achieve The Above Goals, Students Need To Solve As Many Problems As Possible. To Counter The Impression That The Study Of Organic Chemistry Consist Primarily Of Memorizing A Diverse Collection Of Molecules And Reactions, This Book Organizes In Shared Feature And Unifying Concepts Giving Emphasis On Principle That Can Be Applied Again And Again.We Make Our Efforts To Design Our Book In Such A Way That The Students Should Learn To New Settings, Finding Their Way To Solution Rather Than Memorizing The Concepts. Also We Encourage The Students To Keep In Mind The Fundamental Reason Behind The Reactions Of All Organic Compounds: Electrophiles React With Nucleophiles.
