Cyclohexane. Computer graphics representation of a molecule of cyclohexane (chemical formula C6H12),shown in its chair conformational form. Six carbon atoms (yellow) are arranged hexagonally on various planes; hydrogen atoms are white. A planar hexagon,however,would require a carbon-carbon (C-C) bond angle of 120 degrees,resulting in a highly strained form. Through rotation about the C-C bond,cyclohexane is able to exist in two "puckered" forms which are completely free from strain,known as chair and boat conformations. Cyclohexane exists pre- dominantly in the chair form as this corresponds to a lower (more stable) energy value. Compare A705/016 showing boat form | |
