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
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
