The FTIR spectrum indicates the presence of a carboxylic acid (broad peak at 3200 cm-1) and a carbonyl group (strong peak at 1720 cm-1). The 1H NMR spectrum shows complex splitting patterns, suggesting multiple hydrogen environments. By comparing these spectral features with the provided candidates, we conclude that the compound is CH3CH2C(H)(CH3)C(H)(CH3)COOH, which matches the spectral data."}
