A ketone was treated with lithium aluminum hydride followed by \\( \\mathrm{H}_{3} \\mathrm{O}^{+} \\). Explain what you would look for in the IR spectrum of the product to verify that the expected reaction had occurred. Identify which signal(s) should be present and which signal(s) should be absent. Select all that apply. Disappearance of a signal \\( -1700 \\mathrm{~cm}^{-1} \\). Disappearance of a signal \\( -3100 \\mathrm{~cm}^{-1} \\). Appearance of a signal \\( -3100 \\mathrm{~cm}^{-1} \\). Appearance of a signal \\( -1700 \\mathrm{~cm}^{-1} \\). Appearance of a broad signal between 3200 and \\( 3600 \\mathrm{~cm}^{-1} \\). Appearance of a broad signal between 2200 and \\( 3600 \\mathrm{~cm}^{-1} \\). Appearance of a sharp signal \\( -3300 \\mathrm{~cm}^{-1} \\). Disappearance of a sharp signal \\( -3300 \\mathrm{~cm}^{-1} \\).
