Question

Do the following conversions in not more than two steps:

\[\begin{array}{cc}
\ce{CH3CN to CH3 - C - CH3}\\
\phantom{...........}||\\
\phantom{...........}\ce{O}
\end{array}\]

Answer 1

\[\begin{array}{cc}
\phantom{.............................}\ce{Cl}\\
\phantom{.................................}\backslash\\
\ce{CH3 - C ≡ N + CH3MgCl -> CH3 - C = NMgCl + 2H2O ->[H+] Mg + NH3 + CH3 -C - CH3}\\
\phantom{................................}|\phantom{.......................}/\phantom{....................}||\phantom{..}\\
\phantom{..............................}\ce{CH3}\phantom{.................}\ce{OH}\phantom{.....................}\ce{O}\\\\\\\phantom{.}\\
\end{array}\]
