Discussion Overview
The discussion centers around whether glucose in its cyclic structure can react with hydrogen iodide (HI) to form n-hexane. Participants explore the chemical reactions involved, including the potential reduction of glucose and the energy considerations associated with such transformations.
Discussion Character
Main Points Raised
- One participant questions if glucose in its cyclic structure reacts with HI to produce n-hexane, referencing the open chain structure's reaction with HI.
- Another participant agrees that glucose could be reduced to n-hexane, suggesting that an O-C bond would break and hydroxyl groups would be removed, although they express uncertainty about the technical details.
- A third participant argues against the reaction, citing a significant energy requirement (one and a quarter megajoules per mole) that suggests the reaction does not occur.
- In response, a participant asks for clarification on the reasoning behind this claim.
- Another participant elaborates that the reaction involves moving from a partially oxidized state to a fully reduced state, which requires energy that HI alone cannot provide.
- One participant humorously suggests that energy input, such as heat, could change the outcome, while agreeing that HI alone is insufficient for reduction.
- A later reply states that with enough energy, it is theoretically possible to convert various organic molecules into others, but practical challenges such as yield and cost would be significant.
Areas of Agreement / Disagreement
Participants express differing views on the feasibility of glucose reacting with HI to form n-hexane, with some supporting the idea of reduction and others arguing against it based on energy considerations. The discussion remains unresolved with multiple competing perspectives.
Contextual Notes
Participants reference energy requirements and the nature of chemical transformations without fully resolving the underlying assumptions or providing detailed mechanisms for the proposed reactions.
