Q. Which conformer of butane molecule has lowest energy?
Hydrocarbons
A
Ellipsed
32%
B
Skew
20%
C
Staggered
26%
D
Anti staggered
23%
Solution:
Relative stability order of conformers of butane anti staggered $>$ Gauche $>$ Partial Eclipsed $>$ Fully Eclipsed
Stability $\propto \frac{1}{\text { energy }}$
So Anti staggered has lowest energy
