Question
Write a classification of aliphatic ketones with a suitable example.
✓
Answer
On the basis of types of alkyl groups bonded to carbonyl carbon, aliphatic ketones are further classified as simple and mixed ketones.
Simple or symmetrical ketones: The ketones in which both the alkyl groups bonded to carbonyl carbon are identical are called simple ketones or symmetrical ketones.
e.g.
Simple or symmetrical ketones: The ketones in which both the alkyl groups bonded to carbonyl carbon are identical are called simple ketones or symmetrical ketones.
e.g.
- $\begin{array}{cc}
\ce{O}\phantom{.......}\\
||\phantom{.......}\\
\ce{\underset{\text{Dimethyl ketone (Acetone)}}{H3C - C - CH3}}
\end{array}$ - $\begin{array}{cc}
\ce{O}\\
||\\
\ce{\underset{\text{Diethyl ketone}}{H5C2 - C - C2H5}}
\end{array}$
Mixed or unsymmetrical ketones: The ketones in which two alkyl groups bonded to carbonyl carbon are different are called mixed ketones or unsymmetrical ketones.
e.g.
- $\begin{array}{cc}
\ce{O}\phantom{..}\\
||\phantom{..}\\
\ce{\underset{\text{Ethyl methyl ketone}}{H5C2 - C - CH3}}
\end{array}$ - $\begin{array}{cc}
\ce{O}\phantom{.............}\\
||\phantom{.............}\\
\ce{\underset{\text{Ethyl n-propyl ketone}}{H5C2 - C - CH2 -CH2 - CH3}}
\end{array}$
