Side chains chemistry
WebOxidation of Alkyl Side-Chains. As noted earlier in section 16.1, alkyl side chains are activated towards oxidation at the benzylic position, because free radicals are stabilized at that position through resonance (see section 16.4.). When heated with aqueous potassium permanganate (KMnO 4) under acidic conditions, alkylbenzenes are oxidized to benzoic … WebJun 20, 2024 · 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).
