# What is the difference between "organic chemistry", and "inorganic chemistry"?

$\text{Organic Chemistry}$ includes the chemistry of carbon bound to hydrogen, nitrogen, oxygen, (and a few heteroatoms). While this field sounds restricted it includes an entire biological chemistry. And thus an organic compound is typically, ${C}_{n} {H}_{m} {N}_{p} {O}_{l}$.
$\text{Inorganic Chemistry}$ includes the rest of the Periodic Table. $\text{Organometallic chemistry}$ includes carbon bound to metal atoms, so inorganic chemists often work with highly reactive carbon compounds.
