Document Summary
Bond making tends to release heat (exothermic) Radical stability determines the c-h bond strength: tertiary carbons are the most stable radicals therefore the energy required to create them decreases. The deprotonation of a methyl causes a nearly planar geometry. Hyperconjugation bonding pairs of electrons found in the sigma orbitals can delocalize into the partly empty p orbital and therefore stabilize it: hyperconjugation makes the radical more stabilized and easier to get to. The function of a catalyst: allows the process to occur at a lower temperature thereby affecting the reaction kinetics as well as help select for certain products, catalysts do not change the overall thermodynamics of a reaction. In order to get more gas, the oils with higher boiling points are cracked by pyrolysis. 3. 4 chlorination of methane: the radical chain mechanism. Chlorination reactions a reaction where radicals play a key role produces chloromethane and hydrogen chloride.
