Phenols . are compounds of the general formula . Ar. -OH, where . Ar. - is phenyl, substituted phenyl, or one of the other aryl groups. . I. Structure . and nomenclature:. Phenols . differ from alcohols in having the -OH group attached directly to an aromatic . The Ultimate Reality. The Universe and Us, Neeti Sinha. 1. How all that exists is merged into one. 2. The Universe and Us, Neeti Sinha. The Ultimate Reality. Why?. All that we see around us, including ‘ourselves’ is ‘real.’ So why do we have the notion of ‘The Ultimate Reality’?. In a phenol the OH group is directly attached to the benzene ring. . In a phenol the lone pair of electrons on the oxygen is delocalised with the electron charge cloud of the . arene. ring. . The delocalised bonding changes the reactivity of the OH group and the . Objective:. To know what phenol is. Success criteria:. Recognise phenol compounds. Recall . the reaction of phenol with bromine water. Compare the reactions of phenols to that of bromine. Explain the difference in reactivity between phenols and benzene. Regulatory. .

Phenolic resins are obtained by the reaction of phenols with aldehydes. Both parent compounds, phenol and formaldehyde, are by far the most important components in commercial phenolic resin production .
