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)
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 thats wrong too.
