” Cyclohexane is a saturated hydrocarbon with Six Carbon atoms present in it

 All carbon atoms are Attached together by single covalent bonds with another carbon to form a ring. They are also called as Alicyclic Compounds “

Cyclohexane – An Overview :

 

The molecular Formula of Cyclohexane is C₆H₁₂

Number of Carbon = 6

Number of Hydrogen = 12

The cyclohexane can be easily prepared by the catalytic reduction of benzene and its derivatives

 

•  Boiling Point    –    80.7 ° C

•  Melting Point   –    6.6 ° C

•  IR Spectrum     –    2850 – 3050 cm⁻¹

• Used as Non-Polar Solvent in Laboratory

Conformations Of Cyclohexane :-

•  The Cyclohexane ring can assume in many shapes.

•  A single Cyclohexane Molecule is in a continuous state of flexing and flipping into different shapes or Confirmation.

 

 

•  These Conformations arise due to rotation around carbon-carbon bonds

The Chair form & Boat form are the two extreme cases.

The Stability Of The Conformations Of Cyclohexane:-

•  The stability of the Conformations of Cyclohexane is depend on the Angle Strain or Ring Strain.

•  Higher the value of Angle Strain, Lower will be stability.

 

 

• Among the all possible Conformations of Cyclohexane, The Chair form is Most Stable Cyclohexane.

Because

1. Angle Strain is Zero

2. All C-C bonds are Staggered

3. It requires only minimum energy.

Because

3. It Requires High energy.

 

Energy Level of Cyclohexane Conformers:-

Cyclohexane Form	Ring Strain (Kcal/Mol)
Half Chair Form	10.8
Boat Form	7.0
Twist Boat Form	5.5
Chair Form	0
