What is Compound A in Reaction with Potassium Permanganate & Bromide?

[mathsgeek]

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?

Are you sure it is bromide, not bromine?

What kind of compounds react easily with bromine?

Yeh its bromine, well i know bromine reacts with alkenes and alkynes but it could possibly react with the propanol in a substitution reaction but i am not certain?

Do alkynes and alkenes react with permanganate? Do alkynes and alkenes react with bromine? Do aldehydes react with permanganate? Bromine?
