Respuesta :

that's an aldehyde. As an functional group, they will always have the shape O=CH

Answer: aldehyde

Explanation:

Functional groups are specific group of atoms within molecules that are responsible for the characteristic chemical reactions of those molecules.

1. Amides have functional group [tex]-O=C-NH_2[/tex].

Example: Ethanamide with molecular formula [tex]CH_3CONH_2[/tex]

2. Aledydes have functional group [tex]-O=CH[/tex].

Example: Ethanal with molecular formula [tex]CH_3CHO[/tex]

3. Ketones have functional group [tex]-C=O[/tex].

Example: Propanone with molecular formula [tex]CH_3COCH_3[/tex]

4. Esters have functional group [tex]-O=C-OR[/tex].

Example: methyl ethanoate with molecular formula [tex]CH_3COOCH_3[/tex]
