Draw Newman projections and wedge-and-dash depictions of $\mathrm{x},2$-difluoroethane in the one anti and two different gauche conformations. (a) In a cold environment, where there is not enough energy to overcome the barrier between Gauche A and Gauche B, are these two forms identical (yes or no answer, please)? (b) If you answered "no" to part (a), what is the relationship between Gauche A and Gauche B? (c) On the wedge-and-dash drawings for the anti form and one of the gauche forms (use either one), indicate the dipoles associated with each C-F bond. (d) Which conformation has the larger overall dipole moment?
