JEE Mains · Chemistry · STD 11 - 8.2 Organic chemistry isomerism
Arrange the following conformational isomers of \(n-\)butane in order of their increasing potential energy :
- A \(II <\mathrm{III}<\mathrm{IV}<\mathrm{I}\)
- B \(\mathrm{I}<\mathrm{IV}<\mathrm{III}<\mathrm{II}\)
- C \(II <\mathrm{IV}<\mathrm{III}<\mathrm{I}\)
- D \(\mathrm{I}<\mathrm{III}<\mathrm{IV}<\mathrm{II}\)
Answer & Solution
Correct Answer
(D) \(\mathrm{I}<\mathrm{III}<\mathrm{IV}<\mathrm{II}\)
Step-by-step Solution
Detailed explanation
More stable less potential energy. Stability order : \(I>I I I>I V>I I\) So Potential energy : \(II >\mathrm{IV}>\mathrm{III}>\mathrm{I}\)

- A beaker contains a fluid of density \(\rho \, kg / m^3\), specific heat \(S\, J / kg\,^oC\) and viscosity \(\eta \). The beaker is filled upto height \(h\).
