Why do sugars have higher boiling points than water?

Click For Summary
SUMMARY

Sugars exhibit higher boiling points than water due to their molecular structure and intermolecular forces. In the discussion, it is established that when boiling soda, water evaporates first, leaving sugars at the bottom of the pot. This phenomenon occurs because the boiling point of water is 100°C, while sugars, depending on their type, can have boiling points significantly higher than this. The discussion clarifies that the sugars' presence at the bottom is related to their solid density rather than their boiling point.

PREREQUISITES
  • Understanding of molecular structure and intermolecular forces
  • Basic knowledge of boiling point concepts in chemistry
  • Familiarity with the properties of water and sugars
  • Experience with experimental chemistry techniques
NEXT STEPS
  • Research the boiling points of various types of sugars, such as glucose and sucrose
  • Study the molecular structure of sugars and their impact on physical properties
  • Explore the concept of density and its effects on phase separation in mixtures
  • Investigate the principles of boiling point elevation in solutions
USEFUL FOR

Chemistry students, educators, and anyone interested in the physical properties of substances and their behavior during heating processes.

I recently heard about an interesting chemistry experiment I have yet to try. It involves boiling soda and watching the water rise and the sugars remain at the bottom of the pot. The reason being is sugars have higher boiling points than water. Thus, the water boils first, heats up, and rises to the top of the pot while the sugars stay on the bottom.

First, I was wondering if this scientific reasoning is accurate. Secondly, I was wondering why sugars would have higher boiling points than water. What about their structure, or better yet the structure of water, compels sugars to boil at a higher temperature than water? I do apologize, for my chemistry is a bit weak hahaha.

Please elaborate - is sugar not dissolved and just staying at the bottom? If so, fact that they stay at the bottom has nothing to do with its boiling point, it is mostly about the solid density.
 
I came.across a headline and read some of the article, so I was curious. Scientists discover that gold is a 'reactive metal' by accidentally creating a new material in the lab https://www.earth.com/news/discovery-that-gold-is-reactive-metal-by-creating-gold-hydride-in-lab-experiment/ From SLAC - A SLAC team unexpectedly formed gold hydride in an experiment that could pave the way for studying materials under extreme conditions like those found inside certain planets and stars undergoing...
