Unreactive

Air consists of nearly 80 percent nitrogen (N2) which is, however, extremely unreactive, because the bond between the two is very stable.

Also, alkanes are generally unreactive chemically or biologically, and do not undergo functional group interconversions cleanly.

Chemical PCBs are fairly chemically unreactive, this property being attractive for its application as an inert material.

Chemistry main Fullerenes are stable, but not totally unreactive.

Greenwood and Earnshaw, p. 1255 Monazite is a chemically unreactive phosphate mineral that is found as yellow or brown sand; its low reactivity makes it difficult to extract thorium from it.

In general, alkyls are unreactive and difficult to get to react selectively at the desired positions, with few exceptions.

In such conditions the ice crystals of the cloud provide a suitable surface for conversion of unreactive chlorine compounds into reactive chlorine compounds, which can deplete ozone easily.

Methyl groups can be quite unreactive.

Nitrogen is an unreactive gas because breaking the strong triple bond in the dinitrogen molecule (N 2 ) requires a lot of energy.

The alkyl group is unreactive and the chemical and biological properties are mainly due to the nitrite group.
