WebA nitrile contains a triply bonded C = N group, which is another common type of polar bond. However, the carbon in a nitrile is at an oxidation state of +3, higher than the +2 for ketones or +1 for aldehydes. For this reason, nitriles are not carbonyl equivalents like imines; rather, they are at the same oxidation state as carboxylic acids.

Hydrogenated nitrile butadiene rubber (HNBR) is produced by hydrogenation of NBR. Doing so removes the olefinic groups, which are vulnerable to degradation by various chemicals as well as ozone. Typically, Wilkinson's catalyst is used to promote the hydrogenation. The nitrile groups are unaffected. The degree of hydrogenation determines the kind of vulcanization that can be applied to the polymer. WebViton® vs. Nitrile O-rings – Which to Choose? Industrial Seal.
