Chapter 1-Structure and Bonding Structure • Organic molecules are composed of carbons and hydrogens o Based off a carbon skeleton or backbone, so where ever you see a carbon there will be a hydrogen bonded to it o Simple structure equation: CH2+2 ▪ n is the number of carbon atoms present Periodic Trends • valence electrons: outer shell electrons used for bonding o amount of valence electrons is based on the column (up and down) the element is in • electronegativity: the inward pull by the protons in the nucleus on the electron cloud o smaller molecules are typically more electronegative- it takes less effort from the nucleus to pull on a smaller electron cloud
