Substituted cyclohexane
Did you know?
WebIn examining possible structures for substituted cyclohexanes, it is useful to follow two principles: (i) Chair conformations are generally more stable than other possibilities. (ii) Substituents on chair conformers prefer to occupy equatorial positions due to the increased steric hindrance of axial locations. WebThe synthesis and chemical transformations of 3,6‐disubstituted cyclohex‐2‐enones into new chiral liquid crystalline laterally substituted derivatives of biphenyl, terphenyl or quaterphenyl are presented. The mesomorphic properties of the compounds prepared and physical and electro‐optical parameters of FLC compositions based upon them are …
WebCyclohexane is a cyclic structure made up of six carbons along with hydrogens. This is a colourless and flammable liquid with the chemical formula C6H12.
