Select the correct statements about BHT (butylated hydroxytoluene).
AIt contains a phenolic hydroxyl group.
BTwo tert-butyl groups are present on the carbons adjacent to the hydroxyl-bearing carbon.
CThe radical formed after H-atom donation is a more effective chain carrier than the peroxy radical it replaces.
DIt is added to fats and oils to retard rancidity.
Answer: A, B, D
BHT is 2,6-di-tert-butyl-4-methylphenol, so statements 1 and 2 are true. It is added to retard rancidity (4). Its radical is stabilised and unreactive, so it terminates rather than carries chains, making statement 3 false.
