Three types of bonds are formed between carbon atoms: single bond, double
bond, and triple bond.
Single bond is a covalent bond formed by two carbon atoms sharing two electrons. Compounds with only single bonds between carbon atoms are known as
alkanes.

Double bond consists of two covalent bonds formed by two carbon atoms sharing four electrons. Compounds with at least one carbon–carbon double bonds are
called as alkenes.
Triple bonds comprise of three covalent bonds made by two carbon atoms sharing six electrons. The compounds with at least one triple bond between carbon
atoms are known as alkynes.

The simplest organic compounds are the hydrocarbons, which contain not only
carbon but also hydrogen. Exposure to hydrocarbons may impact human health in
