In chemistry an eclipsed conformation is a conformation in which two substituents X and Y on adjacent atoms A, B are in closest proximity, implying that the torsion angle X–A–B–Y is 0°. [1] Such a conformation can exist in any open chain, single chemical bond connecting two sp 3-hybridised atoms, and it is normally a conformational ...
The term, "flip" is misleading, because the direction of each carbon remains the same; what changes is the orientation. A conformation is a unique structural arrangement of atoms, in particular one achieved through the rotation of single bonds. [2] A conformer is a conformational isomer, a blend of the two words.
The staggered conformation is more stable by 12.5 kJ/mol than the eclipsed conformation, which is the energy maximum for ethane. In the eclipsed conformation the torsional angle is minimised. staggered conformation left, eclipsed conformation right in Newman projection
In psychiatry, derailment (aka loosening of association, asyndesis, asyndetic thinking, knight's move thinking, entgleisen, disorganised thinking [1]) categorises any speech comprising sequences of unrelated or barely related ideas; the topic often changes from one sentence to another.
The chloride ligands are fully eclipsed. Although this geometry results in repulsive interactions between the chloride ions, this conformation allows for maximum δ–δ overlap between the Re(III) centers, a factor which overrides the unfavorable chloride repulsions. The [Re 2 Cl 8] 2− anion has a weak electrophilic character.
In the 1980s, however, Jerry Fodor revived the idea of the modularity of mind, although without the notion of precise physical localizability. Drawing from Noam Chomsky's idea of the language acquisition device and other work in linguistics as well as from the philosophy of mind and the implications of optical illusions, he became a major proponent of the idea with the 1983 publication of ...
More complex molecules, such as butane, have more than one possible staggered conformation. The anti conformation of butane is approximately 0.9 kcal mol −1 (3.8 kJ mol −1) more stable than the gauche conformation. [1] Both of these staggered conformations are much more stable than the eclipsed conformations.
Despair by Edvard Munch (1894) captures emotional detachment seen in Borderline Personality Disorder. [1] [2]In psychology, emotional detachment, also known as emotional blunting, is a condition or state in which a person lacks emotional connectivity to others, whether due to an unwanted circumstance or as a positive means to cope with anxiety.
