This question is about the analysis of organic compounds. For each pair of compounds in Questions 01.1 and 01.2, give a reagent (or combination of reagents) that could be added separately to each compound in a single reaction to distinguish between them. State what is observed in each case. 0 1 . 1 CH3CH2CH2CHO and CH3CH2CH(OH)CH3 [3 marks] Reagent(s) Observation with CH3CH2CH2CHO Observation with CH3CH2CH(OH)CH3 0 1 . 2 Cyclohexane and cyclohexene [3 marks] Reagent(s) Observation w...
