Identify the relationship between the following compounds.Two Newman projections of staggered conformations are shown. The structure on the left is as follows: a front carbon, represented at the centre of a Y$-$fork and a H at the top of Y$-$fork; Br on the lower right arm of Y$-$fork; and CH$3$ on the lower left arm of Y$-$fork. Back carbon is represented as a circle at the back of Y$-$fork and has a H at the bottom of Y$-$fork; OH on the upper right arm of Y$-$fork; CH$3$ on the upper left arm of Y$-$fork. The structure on the right is as follows: a front carbon, represented at the centre of a Y$-$fork and a H at the top of Y$-$fork; CH$3$ on the lower right arm of Y$-$fork; and Br on the lower left arm of Y$-$fork. Back carbon is represented as a circle at the back of Y$-$fork and has a H at the bottom of Y$-$fork; OH on the upper right arm of Y$-$fork; CH$3$ on the upper left arm of Y$-$fork.
