Question

What is a functional group? Give examples of four different functional groups.

Answer 1

Functional groups

• Functional groups are a group of components.
• They are in responsible of the chemical reactions that those molecules have.
• The same functional group will undergo the same or similar chemical reaction regardless of the size of the molecule.

Examples of functional groups

• Alcohol: An alcohol is an organic compound having an aliphatic carbon atom having the hydroxyl, $-\mathrm{OH}$ functional group.
• Ketone: A ketone is a functional group with a carbonyl carbon $-\underset{\mathrm{I}}{\mathrm{C}}=\mathrm{O}$.
• Carboxylic: An organic acid with a carboxyl group is known as a carboxylic acid $-\mathrm{COOH}$.
• Aldehyde: An aldehyde is a functional group with a carbonyl carbon, $\mathrm{H}-\underset{\mathrm{I}}{\mathrm{C}}=\mathrm{O}$
