Question

Name the following functional group:

$-\mathrm{OH},-{\mathrm{NH}}_2,-\mathrm{CHO},-\mathrm{COOH}$

Answer 1

Part: 1:

1. $\mathbf{-}\mathbf{OH}$ is called Hydroxyl/Alcoholic.
2. The compound which is contain a alkyl group attached with the hydroxyl group are called alcohols.
3. For example Ethanol (${\mathbf{C}}_{\mathbf{2}}{\mathbf{H}}_{\mathbf{5}}\mathbf{OH}$ )

Part 2:

1. $\mathbf{-}{\mathbf{NH}}_{\mathbf{2}}$ is called the Amino group.
2. The compound where alkyl group is attached to the amino group is called amines.
3. For example Methylamine (${\mathbf{CH}}_{\mathbf{3}}{\mathbf{NH}}_{\mathbf{2}}$)

Part: 3

1. $\mathbf{-}\mathbf{CHO}$ is called Aldehyde and the group is called Aldehydic group.
2. When the aldehydic group is attached to the chain then the compound is called an aldehydic compound.
3. For example Methanal ($\mathbf{HCHO}$)

Part 4:

1. $\mathbf{-}\mathbf{COOH}$ is called the Carboxyl group.
2. the compound where the carbonyl group is present is called carboxylic acid.
3. For example Ethanoic acid (${\mathbf{CH}}_{\mathbf{3}}\mathbf{COOH}$ )
