Flagpole boat cyclohexane
Did you know?
WebThree conformations of cyclohexane, designated as chair, boat, and skew (or twist), are essentially free of angle strain. Of these three the chair is the most stable, mainly because it has a staggered arrangement of all its bonds. The boat and skew conformations lack perfect staggering of bonds and are destabilized by torsional strain. http://ursula.chem.yale.edu/~chem220/chem220js/STUDYAIDS/movies/cyclohex.html
WebAn additional cause of the higher energy of the boat conformation is that adjacent hydrogen atoms on the 'bottom of the boat' are forced into eclipsed positions. For these reasons, the boat conformation about 30 kJ/mol less stable than the chair conformation. A boat structure of cyclohexane (the interfering "flagpole" hydrogens are shown in red) WebThe interaction between the two flagpole hydrogens, in particular, ... Thus, there are multiple pathways by which a molecule of cyclohexane in the twist-boat conformation can achieve the chair conformation again. …
WebTranscribed Image Text: In the boat conformation of cyclohexane, the "flagpole" hydrogens are located: Select one: on C-1 and C-3. on the same carbon. none of the mentioned on C-1 and C-4. on adjacent carbons.
WebThe boat can alleviate some of its torsional strain by twisting, giving a conformation called a twist boat. [Pg.180] Figure 4.15 (a) Illustration of the eclipsed conformation of the boat conformation of cyclohexane, (b) Flagpole interaction of the Cl and C4 hydrogen atoms of the boat conformation.
Web4. fHow to draw cyclohexane chairs. (1) Begin with the chair conformation of cyclohexane. (2) Draw the axial bonds before the equatorial ones, alternating their direction on adjacent atoms.
