Vedclass · Answer

(B) Carbolic acid is another name for phenol $(C_6H_5OH)$.When phenol is heated with a mixture of concentrated nitric acid $(HNO_3)$ and concentrated sulphuric acid $(H_2SO_4)$,it undergoes electrophilic aromatic substitution (nitration) at the $2, 4,$ and $6$ positions.This reaction results in the formation of $2,4,6$-trinitrophenol,which is commonly known as picric acid.The chemical reaction is as follows:$C_6H_5OH + 3HNO_3 \xrightarrow{conc. H_2SO_4} C_6H_2(NO_2)_3OH + 3H_2O$

When carbolic acid is heated with concentrated nitric acid in the presence of concentrated sulphuric acid,it forms:
