Match each characteristic functional group structure listed on the left with its correspon… — JAMB UTME

Match each characteristic functional group structure listed on the left with its corresponding organic class name on the right.

The correct pairings are:

-\text{NH}_2

matches with Primary amine,

-\text{CONH}_2

matches with Amide,

-\text{O}-

matches with Ether, and

-\text{COOR}

matches with Ester.

Each organic compound class is identified by its specific functional group arrangement:

-\text{NH}_2

specifies primary amines,

-\text{CONH}_2

specifies primary amides, an oxygen atom bridging two carbon groups (

-\text{O}-

) specifies ethers, and

-\text{COOR}

specifies esters.

Identify the amino functional group

-\text{NH}_2

is recognized as an amino group attached to a carbon chain.

Compounds containing the

-\text{NH}_2

group attached directly to an alkyl carbon belong to the class of primary amines.

Identify the carboxamide functional group

-\text{CONH}_2

contains a carbonyl bonded to an amino group.

This structural unit defines the primary amide family.

Identify the ether linkage

-\text{O}-

represents a single oxygen atom bridging two carbon atoms.

An oxygen atom connected to two alkyl or aryl groups (

\text{R-O-R'}

) characterizes an ether.

Identify the ester group

-\text{COOR}

contains a carbonyl carbon attached to an alkoxy group.

This group is derived from an alkanoic acid and an alkanol, forming an ester.
