Step-by-step solution
Free radical inhibitors are substances that react with reactive free radicals to form relatively stable and unreactive radicals, thereby breaking the chain reaction. (A) p-Benzoquinone acts as a free radical inhibitor. It reacts with a free radical to form a highly resonance-stabilized and unreactive aryloxy radical, which stops the chain reaction. (B) Oxygen ( O ₂ ) is a diradical and acts as a free radical inhibitor. It reacts with highly reactive alkyl radicals to form peroxy radicals ( R-O-O ^ ), which are much
