1. 1 Structure and Structural Formulas of Organic Molecules A molecule is made of atoms that are attached to one another.The order of attachment The atoms are interrelated and interacton each other1.1.1 Molecular formulas

Molecular formula represent the species and the number of the atoms which compose the molecule.

Gilbert Newton LewisGilbert Newton Lewis(1875-1946) was born in Weymouth, Massachusetts,and received his Ph.D. atHarvard in1899. After a shorttime as professor of chemistry at MIT.(1905-1912).He spent the rest of career at the Univ. of California at Berkeley (1912-1946)
