An optically active compound X, C7H12, yields an opticallyactive product Y, C7H16, when treated with excess hydrogen and acatalyst. Treatment of X with Ag(NH3)2 (silver diamine complex),yields a solid Z. When X is treated with H2O/H2SO4, an opticallyactive product W, C7H14O, is formed. Draw the structures of X, Y,Z, and W.
