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).
Nonillion 1,000,000,000,000,000,000,000,000,000,000 (30 zeros). Decillion 1,000,000,000,000,000,000,000,000,000,000,000 (33 zeros). The number Googol (termed by Milton Sirotta) has 100 zeros after it, then there is the number Googolplex, a 1 followed by a googol of zeros. This list goes on and on.he number Googol (termed by Milton Sirotta) has 100 zeros after it, then there is the number Googolplex, a 1 followed by a googol of zeros.
