Alkane Formulas All C-C single bonds Saturated with hydrogens Ratio:H n2n+2 Alkane homologs:ch3(ch2)nCH3 Same ratio for branched alkanes

To determine reaction''s mechanism, look at: Equilibrium constant Free energy change Enthalpy Entropy Bond dissociation energy Kinetics >Activation energy

Wave Properties of Electrons Standing wave vibrates in fixed location. Wave function, w, mathematical description of size, shape, orientation Amplitude may be positive or negative Node: amplitude is zero

Functional Group Pi bond is the functional group. · More reactive than sigma bond. · Bond dissociation energies:

Types of Alcohol Reactions HH H Dehydration to alkene ·xidation to aldehyde, ketone Substitution to form alkyl halide Reduction to alkane ·Esterification ·Tosylation Williamson synthesis of ether

Definitions Conjugated double bonds are separated by one single bond. Example: 1, 3-pentadiene. Isolated double bonds are separated by two or more single bonds. 1, 4-pentadiene. Cumulated double bonds are on adjacent carbons. Example: 1, 2-pentadiene
