As we learnt in 

Conformations -

Different arrangement of atoms in a molecule which can be obtained due to rotation about carbon - carbon single bond.

- wherein

This type of isomerism is found in alkanes and cycloalkanes and their substituted derivatives.

Which type of strain is present in fully eclipsed conformation of butane?

  • Option 1)

    Angle strain

  • Option 2)

    Steric Strain

  • Option 3)

    Both a & b

  • Option 4)

    Neither a nor b

 

 

Torsional strain -

The repulsive interaction between the bonds or electron pairs of the bonds on adjacent carbon atoms.

- wherein

Increases the potential energy stored within a molecule making the molecule less stable.

 

 In fully eclipsed conformation of butane angle, a steric and torsional  strain is present


Option 1)

Angle strain

Incorrect

Option 2)

Steric Strain

Incorrect

Option 3)

Both a & b

Correct

Option 4)

Neither a nor b

Incorrect
