Give the dot diagram of the first member of the alcohol.
उत्तर
Methyl alcohol (CH3OH) is the first member of alcohol. Its electron-dot structure is shown below:
\[\begin{array}{cc}
\ce{H}\phantom{...}\\
\ce{H^\bullet_\bullet\overset{\bullet\bullet}{\underset{\bullet\bullet}{C}}^\bullet_\bullet\overset{\bullet\bullet}{\underset{\bullet\bullet}{O}}^\bullet_\bullet H}\\
\ce{H}\phantom{...}
\end{array}\]
