SUMMARY

The discussion focuses on determining the solubility of various compounds in either tetrachloride or water, emphasizing the principle of "like dissolves like." Thiamine hydrochloride, ammonium acetate, ammonia, and the fatty acid CH3(CH2)16CO2H are identified as polar, while C6H12 and CS2 are classified as nonpolar. The participant expresses confusion regarding the classification of ammonium acetate and the long-chain fatty acid, indicating a need for clarity on the polarity of these compounds.

PREREQUISITES
  • Understanding of molecular polarity
  • Familiarity with solubility principles
  • Basic knowledge of organic compounds and their structures
  • Ability to draw and analyze chemical structures
NEXT STEPS
  • Research the polarity of ammonium acetate and its implications for solubility
  • Study the solubility rules for organic compounds in polar and nonpolar solvents
  • Explore the structural characteristics of fatty acids and their solubility behavior
  • Learn about the properties of solvents like tetrachloride and water in chemical reactions
USEFUL FOR

Chemistry students, educators, and anyone interested in understanding solubility and molecular interactions in solvents.

Homework Statement


Which solvent would be a better choice to dissolve each of the following?
Tetracholride or Water
a - thiamine hydrochloride
b - CH3(CH2)16CO2H
c - C6H12
d - CS2
e - NH3
f - (NH4)(CH3CO2)



Homework Equations


Draw the structure and find polarity
Like dissolve like

The Attempt at a Solution


I know water is polar, so will be soluble with other polar molecules
I know tetrachloride is nonpolar, soluable with non polar.

a - thiamine hydrochloride - Polar b/c Vitamin B and C are water soluable, and structure
b - CH3(CH2)16CO2H - Polar b/c CO2H end of chain
c - C6H12 - non polar
d - CS2 - non polar because structure
e - NH3 - polar
f - (NH4)(CH3CO2) - polar b/c CH3CO2

Clearly I have gone somewhere as the answer is wrong. I really don't know if F is right. And also B because it is a long chain of C-H which are not polar.
I have also tried with B and F as non-polar and that's wrong too.

I assume that you must get all of them right or the program marks the entire problem as wrong.

Only one of your answers is wrong, not two. 'F' is ammonium acetate... a salt. Polar or non-polar?
