प्रश्न
Name the functional group which always occurs in the middle of a carbon chain.
उत्तर
The functional group which always occurs in the middle of the carbon chain is the ketone group (-CO-). In a ketone, a carbon atom is bonded to one oxygen through a double bond. The two remaining free electrons in the carbon atom are shared with two different alkyl groups. This is why the -CO- group always occurs in the middle of the carbon chain.
