Electronegativity and polarity

  • The beginning student in Organic Chemistry is often overwhelmed by facts, concepts, and new language. Each year, textbooks of Organic Chemistry grow in quantity of subject matter and in level of sophistication. This Schaum’s Outline was undertaken to give a clear view of first-year Organic Chemistry through the careful detailed solution of illustrative problems. Such problems make up over 80% of the book, the remainder being a concise presentation of the material. Our goal is for students to learn by thinking and solving problems rather than by merely being told....

  • In IONIC BONDING the valence electrons are completely transferred from one atom to the other atom. Ionic bonds occur between metals and nonmetals when there is a large difference in electronegativity. In COVALENT BONDING the valence electrons are shared as pairs between the bonded atoms. Pure covalent bonding only occurs when two nonmetal atoms of the same kind bind to each other. When two different nonmetal atoms are bonded or a nonmetal and a metal are bonded, then the bond is a mixture of covalent and ionic bonding called polar covalent bonding.
