Question
Consider 3-methylpentane.
Using a Newman projection formula, draw the
most stable conformation of a molecule of this, sighting along the C₂-
C3 bond. Compute the total strain energy for this conformation. Refer to
strain energy values given below
Strain energies with respect to atoms/groups bonded to C-C (one
atom/group bonded to each C)
H <---> H eclipsed: 4 kJ/mol
CH3 <---> H eclipsed: 6 kJ/mol
CH3 <----> CH3 eclipsed: 11 kJ/mol
CH3 <----> CH3 gauche staggered: 3.8 kJ/mol
Select one:
OA. 3.8 kJ/mol
OB. 10 kJ/mol
O C. 11.4 kJ/mol
O D. 7.6 kJ/mol
OE. 15.2 kJ/mol
