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).
Surprisingly, only 70 people. 3. But a googol isn't the largest named number. A googol is 1.0 x 10 - a one followed by 100 zeros. An even bigger number is the googolplex, which is 1.0 x 10googol-a one followed by a googol of zeros. Now, let's get an idea about the size of a googolplex. Ok, let's stop there.
