Observe the following set of reactions
\[
Y \xrightarrow[\text{NaNH}_2(l)]{} \mathrm{C_2H_2}
\xrightarrow[\mathrm{H_2}/\mathrm{Pt}]{} X
\]
Hybridization of carbon in \(X\) and \(Y\), respectively is
Show Hint
Hybridization of carbon:
\begin{itemize}
\item Single bond \(\rightarrow sp^3\)
\item Double bond \(\rightarrow sp^2\)
\item Triple bond \(\rightarrow sp\)
\end{itemize}
Hydrogenation converts multiple bonds into single bonds, increasing the hybridization from \(sp\) to \(sp^3\).
