WebPentane is an organic compound with the formula C 5 H 12 —that is, an alkane with five carbon atoms. The term may refer to any of three structural isomers , or to a mixture of them: in the IUPAC nomenclature, however, pentane means exclusively the n -pentane isomer; the other two are called isopentane (methylbutane) and neopentane … WebNo headers. Now let us consider butane, a slightly larger molecule. There are now three rotating carbon-carbon bonds to consider, but we will focus on the middle bond between C 2 and C 3.Below are two representations of butane in a conformation which puts the two CH 3 groups (C 1 and C 4) in the eclipsed position.. This is the highest energy …

"WebSo in general, the staggered conformation is going to be more stable. It's going to have a lower potential energy. You can imagine that if you start with an eclipsed conformation, these guys are all going to want to get away from each other. So it's kind of like this is the wound conformation. It has higher potential energy. " - Highest energy conformation of pentane
