Learn how polarity is a separation of electric charge in molecules or chemical groups, and how it depends on electronegativity differences. Find out how to classify bonds as polar, nonpolar, or ionic, and how to measure bond dipole moments.
Learn about the three-dimensional arrangement of atoms in a molecule, including bond lengths, bond angles, torsional angles and other geometrical parameters. Find out how molecular geometry is determined by spectroscopic methods, quantum chemistry methods and thermal excitation.
A carbon–oxygen bond is a polar covalent bond between atoms of carbon and oxygen. [1] [2] [3]: 16–22 Carbon–oxygen bonds are found in many inorganic compounds such as carbon oxides and oxohalides, carbonates and metal carbonyls, [4] and in organic compounds such as alcohols, ethers, and carbonyl compounds.
Electronegativity is the tendency of an atom to attract shared electrons in a chemical bond. Learn about the Pauling scale, which ranks elements from 0.79 to 3.98 based on bond energies, and other methods of calculation.
Learn about the different types of chemical bonds, such as covalent, ionic and metallic, and how they are formed and described by quantum theory. Find out the properties and examples of molecules and substances that result from various bonding mechanisms.
Learn about the structure and properties of tetrahedral molecules, which have four substituents around a central atom at the corners of a tetrahedron. Find examples of tetrahedral molecules in main group, transition metal, and water chemistry, as well as exceptions and distortions.
Covalent bonds are also affected by the electronegativity of the connected atoms which determines the chemical polarity of the bond. Two atoms with equal electronegativity will make nonpolar covalent bonds such as H–H. An unequal relationship creates a polar covalent bond such as with H−Cl.
Learn how to measure the tendency of an acid to dissociate into a proton and an anion, and the factors that affect acid strength. Find out the difference between strong and weak acids, and see the values and examples of common acids in water and DMSO.
