Theory of PH The quantitative measurement of the acidity or basicity of a solution is called pH of the solution. It is defined as the negative logarithm of hydrogen ion concentration of a solution. pH = -log [ H+ ] If the pH of a solution is 7, the solution is called neutral. The pH of pure water is 7. The neutral solution has an equal quantity of H+ & OH− ions in pure water. The following relation exists. In logarithmic form: pH +…

Structural Formula
The structural formula of a compound is a drawing that indicates which atoms are connected to which connectivities. Several kinds of structural formulas are used to represent organic compounds: dot formulas (Lewis structures), dash formulas, condensed formulas, combination (of dash and condensed) formulas, and bond-line formulas. “A Structural Formula is a two dimensional structural representation that shows how the various atoms in a molecule are bonded to each other.”Two types of Structural Formula are depicted below. An Expanded Structural Formula is a structural formula that show all atoms in a molecule and all bonds connecting the…
