কোন বিক্রিয়াটি সঠিক?

$\begin{array}{l} \mathrm{C}_{2} \mathrm{H}_{5} \mathrm{OH}(\mathrm{l})+\mathrm{H}_{2} \mathrm{SO}_{4}(\mathrm{l}) \rightarrow \mathrm{C}_{2} \mathrm{H}_{5}- \\ \mathrm{OSO}_{3} \mathrm{H}(\mathrm{l})+\mathrm{H}_{2}(\mathrm{~g}) \end{array}$

$\begin{array}{l} \mathrm{C}_{6} \mathrm{H}_{5}-\mathrm{C} \equiv \mathrm{N}+2 \mathrm{H}_{2} \mathrm{O} \stackrel{\mathrm{HCl}}{\longrightarrow} \mathrm{C}_{6} \mathrm{H}_{5}-\mathrm{COOH} \\ +\mathrm{NH}_{3}+\mathrm{CO}_{2} \end{array}$

$\begin{array}{l} \left(\mathrm{CH}_{3} \mathrm{CO}\right)_{2} \mathrm{O}(\mathrm{l})+\mathrm{NH}_{3}(\mathrm{~g}) \stackrel{\Delta}{\rightarrow} \mathrm{CH}_{3} \mathrm{CO}-\mathrm{NH}_{2}(\mathrm{~s}) \\+\mathrm{CH}_{3} \mathrm{COOH}(\mathrm{l})\end{array}$

উপরের সবগুলো বিক্রিয়াই সঠিক
