उत्तर

Imines are formed when carbonyl compounds react with ammonia derivatives.

\[\begin{array}{cc}
\backslash\phantom{......................}\backslash\phantom{................}\\
\ce{C = O + H2N - Z -> \phantom{.}= N-Z + H2O}\\
\ce{\underset{Compound}{\underset{Carbonyl}{/}}}\phantom{.................}\ce{\underset{Imine}{/}}\phantom{..................}
\end{array}\]

Z = R, , −NH2, −OH, etc.
