A Foundation Course for College Organic Chemistry
To understand and improve the underlying principles that govern how organic reactions occur, A Foundation Course for College Organic Chemistry follows a brick-by-brick building approach. Emphasis is given to interrelating experimental facts and findings with predictions (mechanism) and inferences (results). Discussions focus on clarifying how complex organic reactions occur, which is based on electronegativity differences, movement of electrons (through σ framework or π bonds), and addition or removal of atoms (hydrogen, halogens) or groups (hydroxy, amino). The book begins with simple rules governing the deconstruction of reactions and applies them to explain how esterification, amide, and cyanide hydrolysis reactions proceed. The importance of stereochemistry (used in drug development, biology, and medicine), aromatic electrophilic and nucleophilic substitutions, reaction kinetics, and dynamics is explained with suitable examples. Features: A systematic and structured approach is used to study all aspects of reactive intermediates (generation, structure, geometry, and reactions of carbocations, carbanions, and carbon-free radicals) This book incorporates scientific methods to deduce reaction mechanisms with simple and relevant explanations, and limitations A proper explanation is given to understand the influence of functional groups on the stability and reactivity of intermediates, pKa, HSAB principles, structure-activity relations, and how these can be exploited in organic chemistry Information is presented in an accessible way for students, teachers, researchers, and scientists
Assessing Human Exposure to Key Chemical Carcinogens

This book introduces an effective, affordable, non-invasive, and quick method to detect exposure to dangerous chemical carcinogens, which cause life-threatening conditions like cardiovascular, endocrine, neurological, hematological, dermatological, and malignant diseases. Nearly 20 million people are diagnosed with cancer annually, with almost 10 million deaths. While eliminating carcinogens completely is impossible, improving detection and monitoring—especially through specialized urine analysis—can help define preventive measures to lower carcinogen levels in the body. The chemical carcinogens discussed have been used for decades without proper evaluation of their health effects, costing millions of lives. Considering the long-term health impacts of current products is critical. Early detection is crucial as most carcinogens have cumulative effects. Identifying urinary markers of exposure can help detect, eliminate, or reduce sources of carcinogens, advancing preventive oncology. The book focuses on Group 1 chemical carcinogens classified by the International Agency for Research on Cancer (IARC). The described methods are highly effective, affordable, and applicable in any location with HPLC (High-Performance Liquid Chromatography) and ICP (Inductively Coupled Plasma) devices. They are non-invasive, requiring only urine samples, quick, and inexpensive. This volume aims to develop, improve, and implement screening methods for malignant diseases. It supports medical professionals in interpreting HPLC and ICP urinary analyses and providing guidance on reducing or avoiding carcinogen exposure. In some cases, doctors may identify sources of exposure and inform authorities to address and eliminate these hazards.
