anonymous · Answer

here it is: http://www.acdlabs.com/iupac/nomenclature/79/r79_933.htm The first rule says: (a) Maximum number of substituents corresponding to the principal group.

anonymous · Answer

In this case the prinicpal group is Cl and Br so we need to take the chain that contains the max number of this principal group as the parent chain according to this rule of identifiyng the parent chain.

frostbite · Answer

Reactionrate, we do not consider the Cl and Br as functional groups with priority over alkanes therefor we should always take the longest alkane chain.
