I was wondering does bromide react with propanol or propanal at all? Also, what answers do people get for this question, i say it either propanol or propanal as i don't know if either reacts with bromide and both would be a suitable answer. The question is: Compound A has a molar mass between 55 and 65 and reacts with Potassium pergamanate to produce product B. However, compound A does not react with bromide. Compound B then reacts with a carbonate to create a colourless gas (most likely carbon dioxide). What is Compound A?
