$\mathrm{ZnCl}_{2} / \mathrm{HCl} ; \mathrm{FeCl}_{3} ;$ Alcoholic $\mathrm{HCN}$
$\mathrm{Br}_{2}$ / water; $\mathrm{ZnCl}_{2} / \mathrm{HCl} ; \mathrm{FeCl}_{3}$
Alcoholic $\mathrm{HCN} ; \mathrm{NaOCl} ; \mathrm{ZnCl}_{2} / \mathrm{HCl}$
$\mathrm{Br}_{2} /$ water; $\mathrm{ZnCl}_{2} / \mathrm{HCl} ; \mathrm{NaOCl}$
Correct Option: , 4
Solution:
Novestrol has phenolic, alcoholic and terminal alkyne groups, so it can react with $\mathrm{Br}_{2}$ water, $\mathrm{ZnCl}_{2} l \mathrm{HCl}$ as well as $\mathrm{FeCl}_{3}$.
