Carbon compounds

Organic compounds

• are made only of carbon

• contain carbon bonded to hydrogen and nothing else

• contain carbon bonded to hydrogen

• contain only oxygen

Which property of carbon is important in the forming of many types of organic compounds

• carbon has 6 electrons

• carbon has 6 protons

• carbon has 4 valence electrons

• carbon can only bond with hydrogen

What different physical forms of carbon exist?

• Graphite

• Diamond

• Fullerene

• Amorphous

What elements make up 97% of all living things?

• Oxygen, carbon, helium & nitrogen

• Oxygen, calcium, hydrogen & nitrogen

• Oxygen, carbon, hydrogen & nitrogen

• Iron, carbon, hydrogen & nitrogen

Because carbon has 4 valence electrons....

• it can form up to 4 covalent bonds

• it can form ionic bonds

• it can form only double bonds

• it can form covalent bonds with H only

This is an example of a

• straight carbon chain

• branched carbon chain

• carbon ring structure

• twisted carbon chain

How many covalent bonds does each carbon have in the molecule shown?

• 4

• 2

• 8

• 6

The carbons circled in red...

• are double bonded

• are sharing two pairs of electrons

• are sharing three pairs of electrons

• form a single covalent bond

Which is used as a cutting tool and in jewelry?
