In a competition reaction, equimolar amounts of the four alkanes shown were allowed to react with a limited amount of Cl_2 at 300 degree C. Which one of these alkanes would be depleted most from the mixture? propane pentane butane 2-methylpropane
Substitution of alkanes proceed by free radical mechanism. The tertiary radical is more stable and is most likely yo form hence the reaction that involves this radical will proceed faster. This will lead to faster depletion of the 2-methyl propane compared to the other alkanes present.
