Answer: The correct answer is amine.
Explanation:
All the given options are a type of functional groups. These are defined as the groups which change the
For the given choices:
Ether: These functional group has single bonded oxygen t two carbon atoms. This group is written as [tex]R-O-R'[/tex] where R and R' can be alkyl or aryl groups.
Amine: In this functional group, nitrogen is bonded to carbon atom by single bond. This nitrogen atom can be bonded to one, two or three carbon atoms and are named as primary (1°), secondary (2°) and tertiary (3°) compounds respectively. They are written as [tex]RNH_2,R_2NH\text{ and }R_3N[/tex] respectively.
Ester: In this functional group, two oxygen atoms are present with a carbon atom. One oxygen atom is single bonded to carbon atom and other one is doubly bonded to it. It is written as [tex]R-COO-R'[/tex] where R and R' can be alkyl or aryl groups.
Ketone: In this functional group, one oxygen and one carbon atom is present. The oxygen atom is doubly bonded to carbon atom and the carbon atom is further joined to two alkyl or aryl groups. This is written as [tex]R-CO-R'[/tex]
Hence, the correct answer is Amine.
