### Classification of Butane ConformationsGiven the wedge and dashed conformers of butane, classify each conformation.**Conformers:**- **Conformation 1:** ![Conformation 1](data:image/png;base64,...)- **Conformation 2:** ![Conformation 2](data:image/png;base64,...)- **Conformation 3:** ![Conformation 3](data:image/png;base64,...)### Classification Options- **staggered**- **gauche**- **eclipsed**- **anti**#### Conformation 1 is:- [ ] staggered- [ ] gauche- [ ] eclipsed- [ ] anti#### Conformation 2 is:- [ ] eclipsed- [ ] anti- [ ] gauche- [ ] staggered#### Conformation 3 is:- [ ] eclipsed- [ ] staggered- [ ] anti- [ ] gaucheUse the structural representations provided to determine whether the given conformations of butane fall into the categories of staggered, gauche, eclipsed, or anti. This classification helps in understanding the energetics and stability of different conformers in organic molecules.
