Which Compound Has Highest Boiling Point?

Click For Summary

Discussion Overview

The discussion revolves around identifying which of several chemical compounds has the highest boiling point. The compounds in question include hydrocarbons and alcohols, with a focus on their molecular structures and polarities. The context is primarily homework-related, involving reasoning about boiling points based on molecular characteristics.

Discussion Character

  • Homework-related, Debate/contested

Main Points Raised

  • One participant proposes that CH3—COOH (option C) should have the highest boiling point due to its polarity and the presence of two oxygen atoms.
  • Another participant suggests that H2S (option E) is indicated as having the highest boiling point according to a source, but questions the validity of this claim given that H2S is a gas at standard temperature and pressure (STP).
  • There is a suggestion to verify the boiling points using online resources, such as Wikipedia.

Areas of Agreement / Disagreement

Participants express conflicting views regarding which compound has the highest boiling point, with no consensus reached on the correct answer.

Contextual Notes

There are unresolved assumptions regarding the definitions of boiling points and the conditions under which the compounds are evaluated. The discussion also highlights a potential misunderstanding of the physical state of H2S at STP.

The Attempt at a Solution


Chose C because is more polar with the 2 oxygens, however, the answer has conflicting answer. It says its E while explaining why its C. Can someone confirm which one is right? Thanks!

Ah yes, totally forgot that wikipedia had boiling points, thanks!

So obviously wrong, H2S is a gas at STP.
