Draw all staggered and eclipsed conformations using Newman projections (looking down the C2-C3 bond) as well as line-and-wedged structures of 2-methylbutane. Determine the most stable and least stable conformations. Use the following chart to estimate the relative energies of each conformation.

What rule is used to determine how many covalent bonds an element can form? a. the number of covalent bonds is equal to six c the number of covalent bonds is equal to five minus the group number plus the group number b. the number of covalent bonds is equal to eight d. none of the above minus the group number select the best answer from the choices provided
