Chemistry - Halogen Derivative Question with Solution | TestHub

Hint :
In acidic medium, only monohalogenation takes place. $\begin{array}{rl}& \mathrm{Y}:{\mathrm{CHBr}}_3\\ & \mathrm{Z}:{\mathrm{CH}}_3\mathrm{COONa}\end{array}$ Second step is bromoform reaction that takes place here on ${\mathrm{CH}}_3{\mathrm{COCH}}_2-\mathrm{Br}$
