Which Functional Groups Are Present in This Compound?

Click For Summary

Discussion Overview

The discussion revolves around identifying functional groups present in a specific compound, with a focus on the definitions and classifications of these groups. Participants explore the nature of phenol and its relationship to other functional groups, as well as the implications of their presence in the compound.

Discussion Character

  • Homework-related
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant identifies four functional groups: carboxylic acid, ketone, alcohol, and ether, but questions the inclusion of phenol as a functional group.
  • Another participant seeks clarification on the definition of phenol.
  • A different participant describes phenol as a benzene ring with an alcohol functional group, expressing uncertainty about whether it can still be classified as phenol if additional groups are present.
  • One participant notes that any -OH group attached to a benzene ring is considered "phenolic," highlighting that it has distinct properties compared to a standard alcohol.
  • A participant questions whether the answer C is correct, given that ether is not listed among the functional groups.
  • Another participant emphasizes that the focus should be on identifying correct functional groups rather than the completeness of a list.

Areas of Agreement / Disagreement

Participants express uncertainty regarding the classification of phenol and its status as a functional group. There is no consensus on the correct identification of functional groups in the compound, and multiple viewpoints are presented.

Contextual Notes

Participants discuss the definitions of functional groups and their implications, indicating potential limitations in understanding due to varying definitions and the complexity of the compound's structure.

Homework Equations

The Attempt at a Solution


I counted 4 functional groups. I got:
-Carboxylic acid
-Ketone
-Alcohol
-Ether
However, this combination is not available. I was wondering if phenol is a functional group as C seems the most likely option. I thought phenyl is a functional group and phenol isn't.

Thanks!

What is phenol?

Phenol is a benzene with a alcohol functional group attached to it, right? The compound above has the structure of phenol plus more. I am not too sure if you would still call it a phenol as it has more than what I know as phenol. I think phenol is a compound and not a functional group but they included it as an option so I am a bit confused.

Thanks!
 
Any -OH group attached to the benzene ring is considered "phenolic" (and has rather specific properties, different from an alcohol).

I see, so would you say C is the answer despite not having ether as one of the functional groups listed?
 
It is not about "which list is complete" but "which list contains only correct answers".
