Nitro, Nitroso, Nitrate, and Nitrite Compounds, Organic. Reactive groups are categories of chemicals that typically react in similar ways because they are similar in their chemical structure. Each substance with a chemical datasheet has been assigned to one or more reactive groups, and CAMEO Chemicals uses the reactive group assignments to make its reactivity predictions.
The largest  number that has a commonly-known specific name is a googolplex,  which is a 1 followed by a googol zeros, where googol is 10100 (a 1  followed by 100 zeros).
The maximum of a negative number and 0 is 0. Err...well, will give it a try. Seems to me the MAX number in a one number list is itself. Even if it is a negative number it is the highest number in the list. But maybe this is a trick that works.
