  2. Science of Education (book) - Wikipedia

    en.wikipedia.org/wiki/Science_of_Education_(book)

    In the first book Herbart discusses the general aim of education. The teacher is a guide to moral development of students and must create a relationship with the students that enables them to construct an inner censor for good and evil. [2] Herbart also discusses the role of the authority in the education of children.

  3. Haloalkane - Wikipedia

    en.wikipedia.org/wiki/Haloalkane

    In primary (1°) haloalkanes, the carbon that carries the halogen atom is only attached to one other alkyl group. An example is chloroethane (CH 3 CH 2 Cl). In secondary (2°) haloalkanes, the carbon that carries the halogen atom has two C–C bonds. In tertiary (3°) haloalkanes, the carbon that carries the halogen atom has three C–C bonds.

  4. Aryl halide - Wikipedia

    en.wikipedia.org/wiki/Aryl_halide

    In organic chemistry, an aryl halide (also known as haloarene) is an aromatic compound in which one or more hydrogen atoms, directly bonded to an aromatic ring are replaced by a halide. Haloarenes are different from haloalkanes because they exhibit many differences in methods of preparation and properties. The most important members are the ...

  5. Halocarbon - Wikipedia

    en.wikipedia.org/wiki/Halocarbon

    Halocarbon compounds are chemical compounds in which one or more carbon atoms are linked by covalent bonds with one or more halogen atoms (fluorine, chlorine, bromine or iodine – group 17) resulting in the formation of organofluorine compounds, organochlorine compounds, organobromine compounds, and organoiodine compounds.

    The publication is one of the most widely cited texts in environmental chemistry. In 1999, Stumm and Morgan received the Stockholm Water Prize for their contributions in the field. The citation specifically mentioned Aquatic Chemistry where it was described as a "seminal book" that is "used in education all over the world". [18]

  7. Darzens reaction - Wikipedia

    en.wikipedia.org/wiki/Darzens_reaction

    The Darzens reaction (also known as the Darzens condensation or glycidic ester condensation) is the chemical reaction of a ketone or aldehyde with an α-haloester in the presence of a base to form an α,β-epoxy ester, also called a "glycidic ester".

  8. Index of chemistry articles - Wikipedia

    en.wikipedia.org/wiki/Index_of_chemistry_articles

    Chemistry (from Egyptian kēme (chem), meaning "earth" [1]) is the physical science concerned with the composition, structure, and properties of matter, as well as the changes it undergoes during chemical reactions. [2] Below is a list of chemistry-related articles in alphabetical order.

  9. Hydrohalogenation - Wikipedia

    en.wikipedia.org/wiki/Hydrohalogenation

    A hydrohalogenation reaction is the electrophilic addition of hydrogen halides like hydrogen chloride or hydrogen bromide to alkenes to yield the corresponding haloalkanes. [ 1 ] [ 2 ] [ 3 ] If the two carbon atoms at the double bond are linked to a different number of hydrogen atoms, the halogen is found preferentially at the carbon with fewer ...
