The structure of a nitrile: the functional group is highlighted blue. In organic chemistry, a nitrile is any organic compound that has a −C≡N functional group.The name of the compound is composed of a base, which includes the carbon of the −C≡N, suffixed with "nitrile", so for example CH 3 CH 2 C≡N is called "propionitrile" (or propanenitrile).

Nitric oxide (nitrogen oxide or nitrogen monoxide [1]) is a colorless gas with the formula NO. It is one of the principal oxides of nitrogen . Nitric oxide is a free radical : it has an unpaired electron , which is sometimes denoted by a dot in its chemical formula ( • N=O or • NO).
Due to relatively weak N–O bonding, all nitrogen oxides are unstable with respect to N 2 and O 2, which is the principle behind the catalytic converter, and prevents the oxygen and nitrogen in the atmosphere from combusting.
By contrast, the second three tree species, oak, beech and hickory, are associated with microbes that "absorb reactive nitrogen oxides," and thus can have a positive impact on the nitrogen oxide component of air quality. Nitrogen oxide release from forest soils is expected to be highest in Indiana, Illinois, Michigan, Kentucky and Ohio. [19]
The Ministry of Natural Resources and Environment (MONRE, Vietnamese: Bộ Tài nguyên và Môi trường) is a government ministry in Vietnam responsible for: land, water resources; mineral resources, geology; environment; hydrometeorology; climate change; surveying and mapping; management of the islands and the sea.
Nitrite can be reduced to nitric oxide or ammonia by many species of bacteria. Under hypoxic conditions, nitrite may release nitric oxide, which causes potent vasodilation . Several mechanisms for nitrite conversion to NO have been described, including enzymatic reduction by xanthine oxidoreductase , nitrite reductase , and NO synthase (NOS ...
In organic chemistry, a nitrone is a functional group consisting of an N-oxide of an imine. The general structure is R 1 R 2 C=N + (−O −)(−R 3), where R 3 is not a hydrogen. Their primary application is intermediates in chemical synthesis. A nitrone is a 1,3-dipole used in cycloadditions, and a carbonyl mimic.
