Question

A reaction of ethyl amine and acetic anhydride leads to the formation of ______.

Options

• \[\ce{CH3NHCOCH3}\]

• \[\ce{C2H5CONHCH3}\]

• \[\ce{CH3CONHC2H5}\]

• \[\ce{CH3-CH = N - OC2H5}\]

Answer 1

A reaction of ethyl amine and acetic anhydride leads to the formation of \[\underline{\ce{CH3CONHC2H5}}\].

Explanation:

\[\begin{array}{cc}
\ce{CH3CH2 - NH2 + (CH3CO)2O -> CH3 - C - NH - CH2 - CH3 + CH3COOH}\\
\phantom{........}||\\
\phantom{........}\ce{O}
\end{array}\]
