The main difference between the two is the carbon atom. Organic compounds have the carbon atom in their make up; inorganic compounds do not. Organic examples include table sugar (C12H22O11), methane and our DNA. Inorganic examples include table salt (NaCl), quartz and silver. BTW, organic compounds usually have hydrogen atoms bonded to them; those’re called hydrocarbons. And that’s it in a nutshell.
