Understanding Carbon Atoms in Organic Chemistry

What is a functional group?

• A type of bond between carbon atoms.

• An atom or group that bonds to one or more carbon atoms in an organic molecule and contributes a characteristic chemical behavior to the molecule.

• A group of atoms responsible for the color of organic compounds.

• A molecule that provides energy to chemical reactions.

What designates a primary carbon atom?

• A carbon atom bonded to only one other carbon atom.

• A carbon atom that is not bonded to any other carbon atoms.

• A carbon atom bonded to three other carbon atoms.

• A carbon atom bonded to four other carbon atoms.

What is the designation for a carbon atom bonded to two other carbon atoms?

• Secondary

• Tertiary

• Quaternary

• Primary
