Structural Effects on Stability and Reactivity. Organic Chemstry Laboratory Structural Effects on Stability and Reactivity Introduction The concepts of stability and reactivity are fundamental to understanding chemistry. In this chapter we consider first the thermodynamic definition of chemical stability. We then consider chemical kinetics (Section 3.2) and how it can provide information about reactivity. We also explore how structure influences stability and reactivity. We want to learn how

other hydrocarbons belonging to this class can be taken as descendents of methane‚ resulted from the substitution of one or more atoms of hydrogen with hydrocarbon radicals. Therefore‚ if one hydrogen atom from methane is replaced by a methyl radical‚ -CH3‚ the hydrocarbon (superior to methane) will have the composition C2H6‚ named ethane. The alkanes can be: with a continuous chain‚ if all the carbon atoms are bound with at most two other carbon atoms‚ and with a branched chain‚ if one or more carbon
