So in this question, we're asked, what are the relative energies of the three possible staggered confirmation around the c2 -c3 bond and two -three dye methyl butane? so we drew the diagram in problem 42, and we're being asked about the staggered confirmations at the bottom.
00:17
So let's take a look at what kind of interactions we have.
00:20
So for the first one, we have a gaussian interaction between two methyl groups, which we're told has an energy of 3 .8 kilojoules per hole.
00:28
And then for the next one, we have an anti -interaction, which we'll.
00:33
We know we have the lowest energy and we have one gauished interaction.
00:37
We also have a gauge interaction between the methyl and the hydrogen as we have here.
00:50
And we go for the last one, we have three gauce interactions, both with the 3 .8 kilojoules per mole...
