Answer 1

Answer :

2-heptanol compound belongs to alcohol group.

Triethylamine compound belongs to amine group.

Benzoic acid compound belongs to carboxylic acid group.

Decanal compound belongs to aldehyde group.

Explanation :

Alcohol group : It is the class of organic compound in which the hydroxy (-OH) group is attached to a hydrocarbon is known as alcohols.

The general formula of alcohols are, $C_nH_{2n+1}OH$. According to the IUPAC naming, the alcohols are named as alkanols.

Amine group : It is the class of organic compound in which the amine $(-NH_2)$ group is attached to a hydrocarbon is known as amine.

The general representation of amine are, $R-NH_2$. According to the IUPAC naming, the amine are named as alkaneamines.

Carboxylic group : It is the class of organic compound in which the carboxylic (-COOH) group is attached to a hydrocarbon is known as carboxylic.

The general formula of carboxylic are, $C_nH_{2n+1}COOH$. According to the IUPAC naming, the carboxylic are named as alkanoic acids.

Aldehyde group : It is the class of organic compound in which the (-CHO) group is attached to a hydrocarbon is known as aldehyde.

The general representation of aldehyde are, $R-CHO$. According to the IUPAC naming, the aldehyde are named as alkanals.

Answer 2

2-heptanol belongs to alcoholic group.

Triethylamine belongs to amino group.

Benzoic acid belongs to carboxylic group.

Decanal belongs to aldehyde group.
