Phenol exhibit resonance.
Predict the directive influence of -OH group in Benzene ring.

Presence of a nitro group in a benzene ring

Phenol exhibit resonance.Phenol exhibit resonance.

Phenol exhibit resonance. Draw the resonance structures of phenol.

Is there any difference in the resonance effect of -NH_2 group and -NO_2 group on benzen ring? Justify it.

Assertion : Bromination of phenol takes place even in the absence of Lewis acid. Reason : In phenol, OH group attached to benzene ring has highly deactivating effect.

Assertion: Dipolemoment ofphenol is smaller than that of methanol. Reason: In phenol C-O bond is less polar due to electron withdrawing effect of the benzene ring whereas in methanol, C-O bond Is more polar due to electron releasing effect of CH_3 group.

Benzene is an example of a compound exhibiting resonance . Explain the resonance of ozone.
