Question

_____ conformation of n-butane has maximum energy.​

Answer 1

Answer:

eclipsed

Explanation:

the potential energy of n-- butane is maximum for eclipsed conformation.

Answer 2

Eclipsed conformation of n-butane has maximum energy.​

CONFIRMATION:

• Conformations are used to express the different configurations of a  molecule.
• Different conformations used are saw-horse,newmann etc.
• n- butane has four carbon atoms present in it and is a saturated hydrocarbon.
• The confirmation with the highest energy is probably the one with least stability.
• The least stable conformer is the eclipsed conformation due to steric hindrance.
• Hence the conformation of n-butane with maximum energy is eclipsed conformer.
