# Problem: Isopentane (a.k.a. 2-methylbutane) is a compound containing a branched carbon chain. A Newman projection is given for six conformations about the C2-C3 bond of isopentane. On the curve of potential energy versus angle of internal rotation for isopentane, label each energy maximum and minimum with one of the conformations.Show transcribed image text Isopentane (a.k.a. 2-methylbutane) is a compound containing a branched carbon chain.

Eclipsed → largest groups overlap → θ = 0°

• highest energy, lowest stability

Gauche → largest groups are adjacent → θ = 60°

• middle energy, middle stability

Anti → largest groups are opposite to each other → θ = 60°

• lowest energy, most stable
