Please answer the following question: Information: - The formose reaction, discovered by Aleksandr Butlerov in 1861, involves the formation of sugars from formaldehyde. The term formose is a portmanteau of formaldehyde and aldose. - In chemistry, a molecular orbital (MO) is a mathematical function describing the wave-like behavior of an electron in a molecule. This function can be used to calculate chemical and physical properties such as the probability of finding an electron in any specific region. The term "orbital" was introduced by Robert S. Mulliken in 1932 as an abbreviation for "one-electron orbital wave function". At an elementary level, it is used to describe the "region" of space in which the function has a significant amplitude. Molecular orbitals are usually constructed by combining atomic orbitals or hybrid orbitals from each atom of the molecule, or other molecular orbitals from groups of atoms. They can be quantitatively calculated using the HartreeFock or self-consistent field (SCF) methods. - Oxygen is a chemical element with symbolO and atomic number8. It is a member of the chalcogen group on the periodic table and is a highly reactive nonmetal and oxidizing agent that readily forms oxides with most elements as well as other compounds. By mass, oxygen is the third-most abundant element in the universe, after hydrogen and helium. At standard temperature and pressure, two atoms of the element bind to form dioxygen, a colorless and odorless diatomic gas with the formula . This is an important part of the atmosphere and diatomic oxygen gas constitutes 20.8% of the Earth's atmosphere. Additionally, as oxides the element makes up almost half of the Earth's crust. - Alexander Mikhaylovich Butlerov ( ; September 15 , 1828 -- August 17 , 1886 ) was a Russian chemist , one of the principal creators of the theory of chemical structure ( 1857 -- 1861 ) , the first to incorporate double bonds into structural formulas , the discoverer of hexamine ( 1859 ) , the discoverer of formaldehyde ( 1859 ) and the discoverer of the formose reaction ( 1861 ) . He first proposed the idea of possible tetrahedral arrangement of valence bonds in carbon compounds in 1862 . The crater Butlerov on the Moon is named after him . Alexander Butlerov was born in Chistopol into a landowning family . - Alexander Mikhaylovich Butlerov ( ; 15 September 1828 17 August 1886) was a Russian chemist, one of the principal creators of the theory of chemical structure (18571861), the first to incorporate double bonds into structural formulas, the discoverer of hexamine (1859), the discoverer of formaldehyde (1859) and the discoverer of the formose reaction (1861). - A chemical structure determination includes a chemist's specifying the molecular geometry and, when feasible and necessary, the electronic structure of the target molecule or other solid. Molecular geometry refers to the spatial arrangement of atoms in a molecule and the chemical bonds that hold the atoms together, and can be represented using structural formulae and by molecular models; complete electronic structure descriptions include specifying the occupation of a molecule's molecular orbitals. Structure determination can be applied to a range of targets from very simple molecules (e.g., diatomic oxygen or nitrogen), to very complex ones (e.g., such as of protein or DNA). - A chemist (from Greek chm (ia) alchemy + -ist; replacing chymist from Medieval Latin alchimista) is a scientist trained in the study of chemistry. Chemists study the composition of matter and its properties. Chemists carefully describe the properties they study in terms of quantities, with detail on the level of molecules and their component atoms. Chemists carefully measure substance proportions, reaction rates, and other chemical properties. The word 'chemist' is also used to address Pharmacists in Commonwealth English. - An atom is the smallest constituent unit of ordinary matter that has the properties of a chemical element. Every solid, liquid, gas, and plasma is composed of neutral or ionized atoms. Atoms are very small; typical sizes are around 100picometers (a ten-billionth of a meter, in the short scale). - A double bond in chemistry is a chemical bond between two chemical elements involving four bonding electrons instead of the usual two. The most common double bond, that is between two carbon atoms, can be found in alkenes. Many types of double bonds exist between two different elements. For example, in a carbonyl group with a carbon atom and an oxygen atom. Other common double bonds are found in azo compounds (N=N), imines (C=N) and sulfoxides (S=O). In skeletal formula the double bond is drawn as two parallel lines (=) between the two connected atoms; typographically, the equals sign is used for this. Double bonds were first introduced in chemical notation by prominent Russian chemist Alexander Butlerov. - Nitrogen is a chemical element with symbol N and atomic number 7. It was first discovered and isolated by Scottish physician Daniel Rutherford in 1772. Although Carl Wilhelm Scheele and Henry Cavendish had independently done so at about the same time, Rutherford is generally accorded the credit because his work was published first. The name "nitrogen" was suggested by Jean-Antoine-Claude Chaptal in 1790, when it was found that nitrogen was present in nitric acid and nitrates; this name derives from the Greek roots "nitre" and - "to form". Antoine Lavoisier suggested instead the name "azote", from the Greek "no life", as it is an asphyxiant gas; his name is instead used in many languages, such as French, Russian, and Turkish, and appears in the English names of some nitrogen compounds such as hydrazine, azides and azo compounds.
