If the electron pairs in covalent bonds were donated and shared absolutely evenly there would be no fixed local charges within a molecule. Although this is true for diatomic elements such as H 2, N 2 and O 2, most covalent compounds show some degree of local charge separation, resulting in bond and / or molecular dipoles. A dipole exists when the centers of positive and negative charge distribution do not.

Strong and Weak Acids and Bases. Many hardware stores sell "muriatic acid" a 6 M solution of hydrochloric acid HCl(aq) to clean bricks and concrete. Grocery stores sell vinegar, which is a 1 M solution of acetic acid: CH 3 CO 2 H. Although both substances are acids, you wouldn’t use muriatic acid in salad dressing, and vinegar is ineffective in cleaning bricks or concrete.

The formation of ionic charge carriers and their transport in acetic acid (CH 3 COOH): water mixtures have been investigated by 13 C and 1 H NMR. The obtained dissociation constant from the NMR measurements is close to pK a = 4.70 in a highly diluted system which is in full agreement with literature values. The maximum molar concentration of ions (H 3 O + and CH 3 COO −) is found at a water.

Another class of organic molecules contains a carbon atom connected to an oxygen atom by a double bond, commonly called a carbonyl group. The trigonal planar carbon in the carbonyl group can attach to two other substituents leading to several subfamilies (aldehydes, ketones, carboxylic acids and esters) described in this section.

An acid is alternatively defined as a molecule or ion that accepts an electron pair (Lewis acid). One example is trifluoroborane, which has a boron atom capable of accepting an electron pair from ammonia (NH 3) to form NH 3-BF 3. Common inorganic acids include.
