Below is a 3D representation of a cyclohexane (C6H12) molecule, a cyclic compound used in the manufacture of nylon and found in the distillation of petroleum.
The geometry of the molecule depends on the electron groups that have maximum separation. The shapes of molecules or ions can be explained based on valence shell electron pair repulsion (VSEPR) model. This model is mainly applicable to p-block elements.
Before overlapping with 1s orbital of hydrogen, first the atomic orbitals of carbon undergoes hybridization to form hybrid orbitals. The hybrid orbitals involve in bond formation with hydrogen.
The main postulates of VSEPR model is as follows:
(i) The shape of molecule depends on the electron-electron repulsions present in the valence shell of the central atom.
(ii) The repulsive interactions between the electron pairs are in the following order:
(iii) If the central atom forms multiple bonds, then the order of electron–electron repulsions between them is as follows:
The geometrical arrangement of the atoms is molecular geometry.
The geometrical arrangement of the electron groups is electron geometry.
Mixture of one s and three p orbitals is . The geometry of hybridized atom is tetrahedral.
Mixture of one s and two p is . The geometry of hybridized atom is trigonal planar.
Mixture of one s and one p is . The geometry of sp hybridized atom is linear.
The structure of cyclohexane is as follows:
The hybridization around each carbon is labelled as follows:
Thus, the geometry around each carbon atom in cyclohexane is tetrahedral.
Thus, the hybridization around each carbon atoms is .

3. Cyclic compounds The presence of the ring in all but very large ring cyclic molecules prevents full rotation of the ring atoms. For this reason, stereoisomerism may also occur in cyclic molecules. a) Prepare a model of cyclohexane, C6H12. Draw the condensed formula. b) Build a model of methylcyclohexane (C7H14) by replacing one of the hydrogens of cyclohexane with a methyl group. Draw the skeletal formula for methylcyclohexane. 2 c) How many different isomers exist for methylcyclohexane (CyH34)? d)...
