1. Explain how the cyclohexane ring and the cyclohexene ring can be distinguished using IR.

2. An unknown compound has the following data: elemental analysis: 60.00% C, 13.3% H, 26.7% O molecular weight: 60.00 g/mol IR: 3400, 2950, 1460, 1100 cm-1 Draw three structures that are consistent with molecular weight and indicate which is consistent with IR. Assign the bands to justify your answer.
