The reactions involve the addition of HCN, reduction with LiAlH4, reaction with HNO2, and elimination of an inert gas. The hints provided, including the IR spectral data, guide us in narrowing down the candidates. The final answer is 4,5-dimethylcycloheptan-1-one, which fits the criteria based on the transformations and spectral characteristics described."}
