Match each condensed organic structural formula listed on the left with its correct functi… — JAMB UTME

Match each condensed organic structural formula listed on the left with its correct functional group classification on the right.

\text{CH}_3\text{COCH}_3

matches with Alkanone;

\text{CH}_3\text{CH}_2\text{CHO}

matches with Alkanal;

\text{CH}_3\text{CH}_2\text{COOH}

matches with Alkanoic acid;

\text{HCOOCH}_3

matches with Alkanoate (Ester).

Each condensed formula corresponds directly to its functional group family:

\text{CH}_3\text{COCH}_3

is propanone (an alkanone),

\text{CH}_3\text{CH}_2\text{CHO}

is propanal (an alkanal),

\text{CH}_3\text{CH}_2\text{COOH}

is propanoic acid (an alkanoic acid), and

\text{HCOOCH}_3

is methyl methanoate (an ester / alkanoate).

Identify the characteristic functional group in each condensed formula.

\text{CH}_3\text{COCH}_3

has a non-terminal carbonyl

\text{-CO-}

;

\text{CH}_3\text{CH}_2\text{CHO}

has a formyl

\text{-CHO}

;

\text{CH}_3\text{CH}_2\text{COOH}

has a carboxyl

\text{-COOH}

;

\text{HCOOCH}_3

has an ester linkage

\text{-COO-}

Functional groups determine the class of organic compounds.

Match each identified group to its IUPAC homologous series classification.

Non-terminal carbonyl (

\text{-CO-}

) = Alkanone; Formyl (

\text{-CHO}

) = Alkanal; Carboxyl (

\text{-COOH}

) = Alkanoic acid; Ester linkage (

\text{-COO-}

) = Alkanoate (Ester).

IUPAC nomenclature categorizes compounds based on these specific functional group structures.
