hydrocarbon compounds	compounds that contain only Carbon and hydrogen atoms
alkane	branched, straight chain or cyclic saturated- only single bonds formula-CnH2n+2 Pka- >50 react poorly with ionic or polar solvents substances (chemically inactive) virtually insoluble in water Pka >50 physical properties M.P/B.P increases with increasing carbon chain due to (weak London dispersion intermolecular forces between substances where there is no permanent dipole) Reactivity Generally unreactive combustion (burn in a flame) Halogenation (Cl2/Br2) at high temps or high energy light involving radicals proceeding through radical mechanism mechanism initiation-formation of radical propagation-radical used to make another termination-combo of two radical produce a neutral species radical stability the more CH3 groups that can participate in hyperconjugation the more stable the intermediate radical is distribution patterns of product determined by the stability of the intermediate radical number of carbon atoms bonded to the carbon with the lone electron determines what kind of radical it will be ie 3= tertiary 2=secondary 1=primary 0=methyl
