Why Does Compound C Have a Higher Boiling Point Than Compound D?

Click For Summary

Discussion Overview

The discussion revolves around the boiling points of two compounds, referred to as Compound C and Compound D, both of which are alcohols with the same molecular weight. Participants explore the reasons behind the differences in their boiling points, focusing on molecular symmetry, polarity, and intermolecular forces.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant suggests that Compound C's lack of symmetry may contribute to its higher polarity compared to Compound D, potentially leading to stronger intermolecular forces and a higher boiling point.
  • Another participant mentions the importance of hydrogen bonding in butanol, indicating that it may have a higher boiling point due to its ability to participate in reciprocal hydrogen bonding.
  • Some participants express uncertainty about their reasoning and the conclusions drawn from their observations.
  • There are repeated suggestions to consult external resources for definitive answers, indicating a reliance on external data for clarification.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the reasons for the differences in boiling points, and multiple competing views remain regarding the factors influencing these properties.

Contextual Notes

Participants reference molecular weight, symmetry, polarity, and hydrogen bonding, but do not clarify the specific structural details of Compounds C and D. There is also a lack of definitive answers or established conclusions within the discussion.

In the attachment, i think the answer is c). However c) has the same molecular weight as d) and they are both alcohols. Is it that c) is not symmetrical, thus more polar as compared to d) and which is why c) should have a higher boiling point due to the stronger intermolecular forces?

wow you're really racking up the questions. If you want the absolute answer, go to

type up the formulas, all of the official data will be listed. Right now I'm thinking the butanol, however not quite sure; the only one which can particpate in reciprocating hydrogen bonding (each molecule accepts and donates) and has a significantly higher molecular mass (in reference to carbon chains).

Thanks, I was right. But not too sure bout my reasoning though...
 
do you have the answer to these questions? If so what was the answer to this question?

Nope, but i used chemfinder, and it was relevant to my answer, (mentioned in previous posts).
 
and your answer was...
