1) Longest chain: 7 carbon atoms ⇒ heptane
2) 1 methyl substituent + 1 propyl substituent
3) The left end is the closest to a subst.: number the C atoms from the left to the right
4) 2-methyl-4-propylheptane
What is the first step of the halogenation of alkanes?
Radical chain reactions proceed in 3 stages: initiation (homolytic cleavage of the Cl-Cl bond), propagation and termination (radical-radical combination)
How many products do you expect with the halogenation of methylpropane?
