$\mathrm{A}+\mathrm{B} \underset{293 \mathrm{K}}{\overset{{\mathrm{OH}}^{-}}{\to }} 1,3-\mathrm{diphenylprop}-2-\mathrm{en}-1-\mathrm{one}.$

Incorrect statement about the process is

This is a reaction involving two carbonyl compounds, one containing $\mathrm{\alpha }$-hydrogen atoms and other not containing $\mathrm{\alpha }$-hydrogen atoms
