Starting from compound X, the reactions involve the addition of HCN, reduction with LiAlH4, reaction with HNO2, and elimination to yield compound F. The IR spectral data provides clues about the functional groups present in the compounds. By analyzing the transformations and the spectral information, the correct identification of compound F can be made from the provided candidates."}
