Vedclass · Answer

(B) The reaction of phenol with acetone in the presence of concentrated sulphuric acid is an electrophilic aromatic substitution reaction. Two molecules of phenol react with one molecule of acetone to form bisphenol-$A$ $(C_{15}H_{16}O_2)$. The reaction proceeds as follows: $2C_6H_5OH + CH_3COCH_3 \xrightarrow{conc. H_2SO_4} (HOC_6H_4)_2C(CH_3)_2 + H_2O$. This product is bisphenol-$A$,which corresponds to the structure shown in option $B$.

Phenol reacts with acetone in the presence of concentrated sulphuric acid to form a $C_{15}H_{16}O_2$ product. Which of the following compounds is this product?
