Consider 2-methylbutane (isopentane) Sighting along the C2C3 bond: (a) Draw a Newman projection of the most stable

Question:

Consider 2-methylbutane (isopentane) Sighting along the C2—C3 bond:

(a) Draw a Newman projection of the most stable conformation.

(b) Draw a Newman projection of the least stable conformation.

(c) Since a CH3 ↔ CH3 eclipsing interaction costs 11 kJ/mol (2.5 kcal/mol) and a CH3 ↔ CH3 gauche interaction costs 3.8 kJ/mol (0.9 kcal/mol), make a quantitative plot of energy versus rotation about the C2—C3 bond.
