Phenol on treatment with `CO_(2)` in the presence of `NaOH` followed by acidification produces compound X as the major product. X on treatment with `(CH_(3)CO)_(2)O` in the presence of catalytic amount of `H_(2)SO_(4)` produces

When phenol is treated with conc. HNO_(3) in the presence of conc. H_(2)SO_(4) , the product is :

HC-= CH on treatment with NH_(3) in the presence of FE- pyrite produces the following products.

Cinnamci acid is fomed when C_(6)H_(5)-CHO condenses with (CH_(3)CO_(2))O in the presence of

Reaction of phenol with NaOH followed by heating with CO_(2) under high pressure , and subsequent acidification gives compounds X as the major product , which can be purified by steam distillation . When reacted with acetic anhydride in the presence of a trace amount of conc. H_(2)SO_(4) compound X produces Y as the major product . Compound Y is

The treatment of sodium phenoxide with CO_(2) at 400K and 4-7 atmosphere pressure followed by acidification of the reaction product gives :

Ethanol on treatment with ethanenitrile in the presence of conc. H_(2)SO_(4) followed by hydrolysis will yields

What happens when phenol is warmed with CO_(2) in the presence of aqueous NaOH?
