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

Click For Summary

Discussion Overview

The discussion revolves around the reactivity of certain organic compounds, specifically propanol and propanal, with bromide and potassium permanganate. Participants explore the identity of Compound A, which is characterized by a specific molar mass and its reactions with other chemicals, including the production of a colorless gas upon reaction with a carbonate.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant questions whether bromide or bromine is the correct reagent, indicating uncertainty about the reactivity of bromide with propanol or propanal.
  • Another participant suggests that bromine reacts with alkenes and alkynes, and speculates about a possible substitution reaction with propanol, though they express uncertainty.
  • A participant raises questions about the reactivity of alkynes and alkenes with potassium permanganate and bromine, as well as the reactivity of aldehydes with these reagents.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the identity of Compound A or its reactivity with bromide or bromine, indicating multiple competing views and unresolved questions regarding the reactions involved.

Contextual Notes

There are limitations in the discussion regarding the assumptions about the nature of the reactions and the specific conditions under which these compounds may react. The exact identity of Compound A remains unclear, as does the role of bromide versus bromine in the reactions discussed.

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?
