How do you name compounds? Like when do you know when to do bi, tri, hex etc.
Compounds are named on the basis of their number of atoms present. if one atom combine with another atom more than once, mono, bi, tri are used.
for example, CO - carbon monoxide
CO2 is carbon dioxide
N2O is called dinitrogen oxide
NO2 is called nitrogen dioxide
N2O3 is called dinitrogen trioxide
N2O4 is dinitrogen tetroxide
like pent- for 5
and hex for 6
So mono, bi, tri , tetra, penta, hexa are used to show the number if more than one atom present in a molecule.
In organic chemistry, these notations are used to show the number of branches instead of atoms.
Eg:- 2,2-dimethyl pentane- means 2nd carbon contains 2 times methyl group.
