A carbon–nitrogen bond is a covalent bond between carbon and nitrogen and is one of the most abundant bonds in organic chemistry and biochemistry. [ 1 ] Nitrogen has five valence electrons and in simple amines it is trivalent, with the two remaining electrons forming a lone pair. Through that pair, nitrogen can form an additional bond to ...
Nitrogen compounds. The chemical element nitrogen is one of the most abundant elements in the universe and can form many compounds. It can take several oxidation states; but the most common oxidation states are -3 and +3. Nitrogen can form nitride and nitrate ions. It also forms a part of nitric acid and nitrate salts.
The bond order itself is the number of electron pairs (covalent bonds) between two atoms. [2] For example, in diatomic nitrogen N≡N, the bond order between the two nitrogen atoms is 3 (triple bond). In acetylene H–C≡C–H, the bond order between the two carbon atoms is also 3, and the C–H bond order is 1 (single bond).
Imine. In organic chemistry, an imine (/ ɪˈmiːn / or / ˈɪmɪn /) is a functional group or organic compound containing a carbon – nitrogen double bond (C=N). The nitrogen atom can be attached to a hydrogen or an organic group (R). The carbon atom has two additional single bonds. [1][2] Imines are common in synthetic and naturally ...
Nitrogen is a nonmetal and the lightest member of group 15 of the periodic table, often called the pnictogens. It is a common element in the universe, estimated at seventh in total abundance in the Milky Way and the Solar System. At standard temperature and pressure, two atoms of the element bond to form N 2, a colorless and odorless diatomic gas.
CHNOPS. Graphic representation of carbon, hydrogen, nitrogen, oxygen, phosphorus, and sulfur. CHNOPS and CHON are mnemonic acronyms for the most common elements in living organisms. "CHON" stands for c arbon, h ydrogen, o xygen, and n itrogen, which together make up more than 95 percent of the mass of biological systems. [1] ".
Equipment for a study of nitrogen fixation by alpha rays (Fixed Nitrogen Research Laboratory, 1926) The dominant industrial method for producing ammonia is the Haber process also known as the Haber-Bosch process. [69] Fertilizer production is now the largest source of human-produced fixed nitrogen in the terrestrial ecosystem.
Exhaled nitric oxide. Chemical formula of nitric oxide (NO) together with its molecular size (115 pm). In medicine, exhaled nitric oxide (eNO) can be measured in a breath test for asthma and other respiratory conditions characterized by airway inflammation. Nitric oxide (NO) is a gaseous molecule produced by certain cell types in an ...
