The structural formulae of three compounds are given: $\text{C}_3\text{H}_7\text{CHO}$, $\text{C}_2\text{H}_5\text{COCH}_3$, $\text{CH}_2\text{CHCH}_2\text{CH}_2\text{OH}$. Among these compounds, only one will decolourise bromine water. Among these compounds, only one will give a silver mirror with Tollens’ reagent. Which row gives the correct outcomes?
- Adecolourises bromine water: $\text{C}_3\text{H}_7\text{CHO}$; Tollens’: $\text{C}_2\text{H}_5\text{COCH}_3$
- Bdecolourises bromine water: $\text{C}_2\text{H}_5\text{COCH}_3$; Tollens’: $\text{C}_3\text{H}_7\text{CHO}$
- Cdecolourises bromine water: $\text{CH}_2\text{CHCH}_2\text{CH}_2\text{OH}$; Tollens’: $\text{C}_2\text{H}_5\text{COCH}_3$
- Ddecolourises bromine water: $\text{CH}_2\text{CHCH}_2\text{CH}_2\text{OH}$; Tollens’: $\text{C}_3\text{H}_7\text{CHO}$
