Which parent chain should we choose for this structure? is it A or B?
I followed the rule A-2.6, but it still got me confused. Both alternative A and B has the same number of side chains (2 side chains) - rule A-2.6(a). Both alternative A and B has the same number of locants, which are 5 and 6 - A-2.6(b). Both alternative A and B has the same number of carbon in each locants, which are 4 atoms on number 5 and 9 atoms on number 6 - A-2.6(c). Both alternative A and B branched side chains are quite similar, how do we decide? - A-2.6(d)
