Solution

Four functional groups containing oxygen as the heteroatom in it are as follows:
1. Alcohols: The functional group, which is present in alcohol, is -OH. The IUPAC group suffix of alcohol is –ol.
Example: Ethanol

\[\begin{array}{cc}
|\phantom{........}|\phantom{....}\\
\ce{-C-OH-C-OH}\\
|\phantom{........}|\phantom{....}\\
\end{array}\]

2. Aldehydes: The functional group, which is present in an aldehyde, is -CHO. The IUPAC group suffix of an aldehyde is –al.
Example: Formaldehyde

\[\begin{array}{cc}
\phantom{..}\ce{O}\\
|\phantom{...}||\phantom{..}\\
\ce{-C-C-H}\\
|\phantom{......}
\end{array}\]

3. Carboxylic acid: The functional group present in a carboxylic acid is -COOH. The IUPAC group suffix of a carboxylic acid is –oic acid.
Example: Acetic acid

\[\begin{array}{cc}
\phantom{.}\ce{O}\\
|\phantom{...}||\phantom{...}\\
\ce{-C-C-OH}\\
|\phantom{.......}
\end{array}\]

4. Ketones
Examples:- butanone

\[\begin{array}{cc}
\phantom{......}\ce{O}\\
\phantom{........}||\phantom{..}\\
\ce{CH3-CH2-C-CH3}\\
\end{array}\]

Notes

\[\begin{array}{cc}
|\phantom{........}|\phantom{....}\\
\ce{-C-OH-C-OH}\\
|\phantom{........}|\phantom{....}\\
\end{array}\]
