Question

How will the following be obtained? (Give chemical equation):

Ethanol from Grignard's reagent.

Answer 1

Ethanol from Grignard’s Reagent:

\[\begin{array}{cc}
\phantom{...........................}\ce{O}\phantom{....................}\ce{H}\phantom{..............................................}\ce{Br}\\
\phantom{........................}||\phantom{.....................}|\phantom{.............................................}/\\
\ce{\underset{Grignard Reagent}{H3C - Mg - Br} + \underset{Methanal}{H - C - H} ->[dry ether] H3C - C - O - Mg - Br ->[H2O] H3C \underset{Ethanol}{- CH2} - OH + Mg}\\
\phantom{..............................................}|\phantom{.............................................}\backslash\\
\phantom{................................................}\ce{H}\phantom{.............................................}\ce{OH}
\end{array}\]
