Teens & Depression. â 1 Depression is a serious problem today and one of the nationâs leading killers of teenaged boys when the number of cases of suicide it generates are factored into the equation.
The first organic molecules were probably very simple carbon-based molecules made of few atoms. These molecules then combined with other simple molecules to form more complex molecules. Over many years and probably trillions and trillions of chemical reactions, more complex molecules, and more stable molecules, formed.
Functional groups consist of one or more atoms, and they can be atoms of identical or different elements. The simplest organic molecule is one carbon bonded covalently to four hydrogens, CH4. This compound, a gas, is called methane and is a major component of natural gas.
