Draw all the products resulting from the free radical chlorination of 2,4-dimethyl pentane, and predict the relative product distribution. Assume a ratio of 5.5 : 3.75 : 1.0 for the relative reactivity of tertiary to secondary to primary hydrogens in the free radical chlorination of unsubstituted alkanes. Express final ratio of products as a percent (total should add up to 100).

What is the order of reactivity by brominating isopropyl benzene, ethyl benzene, toulene, methylcyclohexane, cyclohexane, tertbutyl benzene. Discuss if the order of reactivity was similar to what was predicted based on radical stability. Also discuss reasons why one of the hydrocarbons would react faster than another based on radical stability
