Answer 1

Phenol is prepared on an industrial scale by treatment of chlorobenzene with dilute aqueous NaOH at 340 degree C under high pressure Elimination reaction gives a triple bond intermediate called benzene So the 3rd structure is the intermediate formed during the reaction

So the 3rd structure is the intermediate formed during the reaction
