  2. n-Butylamine - Wikipedia

    en.wikipedia.org/wiki/N-Butylamine

    n-Butylamine is an organic compound (specifically, an amine) with the formula CH 3 (CH 2) 3 NH 2. This colourless liquid is one of the four isomeric amines of butane, the others being sec-butylamine, tert-butylamine, and isobutylamine. It is a liquid having the fishy, ammonia-like odor common to amines. The liquid acquires a yellow color upon ...

    The molecular formula C 4 H 11 N may refer to: n-Butylamine; sec-Butylamine; tert-Butylamine; Diethylamine; N,N-Dimethylethylamine; Isobutylamine

  4. Lewis structure - Wikipedia

    en.wikipedia.org/wiki/Lewis_structure

    In terms of Lewis structures, formal charge is used in the description, comparison, and assessment of likely topological and resonance structures [7] by determining the apparent electronic charge of each atom within, based upon its electron dot structure, assuming exclusive covalency or non-polar bonding.

  5. Group 13/15 multiple bonds - Wikipedia

    The Power and co-workers later reported the structure of [P(R)=BMes 2 Li(Et 2 O) 2] (R = phenyl, cyclohexane, and mesitylene), which is the first B=P double bond observed in solid state. [6] The synthesis of [P(R)=BMes 2 Li(Et 2 O) 2 ] starts from treating in-situ generated Mes 2 BPHR with 1 equivalent of t-BuLi in Et 2 O, followed by ...

  6. Chemical polarity - Wikipedia

    en.wikipedia.org/wiki/Chemical_polarity

    Polar molecules must contain one or more polar bonds due to a difference in electronegativity between the bonded atoms. Molecules containing polar bonds have no molecular polarity if the bond dipoles cancel each other out by symmetry. Polar molecules interact through dipole-dipole intermolecular forces and hydrogen bonds.

  7. Gilbert N. Lewis - Wikipedia

    en.wikipedia.org/wiki/Gilbert_N._Lewis

    [3] [7] Lewis was best known for his discovery of the covalent bond and his concept of electron pairs; his Lewis dot structures and other contributions to valence bond theory have shaped modern theories of chemical bonding. Lewis successfully contributed to chemical thermodynamics, photochemistry, and isotope separation, and is also known for ...

    Scientists thought that Lake Enigma was frozen from top to bottom. Then they discovered that water—and mysterious lifeforms—existed 11 meters below the surface.

  9. sec-Butylamine - Wikipedia

    en.wikipedia.org/wiki/Sec-Butylamine

    sec-Butylamine is an organic chemical compound (specifically, an amine) with the formula CH 3 CH 2 CH(NH 2)CH 3. It is a colorless liquid. sec-Butylamine is one of the four isomeric amines of butane, the others being n-butylamine, tert-butylamine, and isobutylamine. sec-Butylamine is chiral and therefore can exist in either of two enantiomeric ...
