For example, NO2 is nitrite, while NO3 is nitrate.

And butyl, and you should memorize this, methyl is one, ethyl is two, propyl is three, butyl is four, so we have a four carbon group.

So a 9 butyltetradecane, so it would have butyl over here.

And if we number them, one, two, three, four, five, six, seven, eight, nine, ten, eleven, twelve, thirteen, fourteen, this tells us that the sixth carbon will be butyl, will be a butyl group.

The oxidation state 5 can be obtained if manganese dioxide is dissolved in molten sodium nitrite.

Let's say we have one, two, three, four, so that is our butyl right there, and it's attached to the sixth carbon.

If methyl is one, ethyl is two, propyl is three, butyl is four, so this is a three carbon group, and it's going to be attached to the second carbon on the heptanes.

The process is different from the one implemented in France in Sweden, ethanol is used pure as fuel, whereas in France it is mixed with isobutylene to yield ethyl tertiary butyl ether which is then blended with traditional fuel.

And the reason for this, it turned out, after two or three years' work, was that in the skin we have huge stores not of nitric oxide, because nitric oxide is a gas, and it's released (Poof!) and in a few seconds it's away, but it can be turned into these forms of nitric oxide nitrate, NO3 nitrite, NO2 nitrosothiols.
