Can anyone answer the following:

Which of the following solvents would be soluble in water

a) Carbon tetra chloride
b) Diethyl ether
c) chloroform
d) propanol
e) a & d

I'm pretty sure the answer is D (Propanol).

REASONING:
When I think of molecular water, 2 things come to mind> H-Bonding & Polarity

Carbon tetrachloride is a tetrahydral Non-polar compound (since all the Cl's dipole moments cancel each other out and it does not exhibit H bonding)

Diethyl ether is also non polar (and it does not exhibit hydrogen bonding)

Chloroform is also non-polar since the two bonds that are across from each other cancel out (Also its an organic solvent which forms a diff. layer in h20)

Propanol does have H bonding, and is polar.

Remember: like dissolves like. 👍

D. Propanol has dipole moment and follows the rule "Like dissolves like"

Yes the answer is D and another explanation is that alcohols from carbon atoms 1 to 4 are soluble in water.

i agree the answer is D because it can hydrogen bond with water, but if there was a choice of "b and d" i would pick that to because short ethers can also form hydrogen bonds in water, but note, not as well as alcohols.

You should remember that H-bond is alot stronger than dipole bond. A molecule with dipole bond doesn't dissolve as well as H-bond.

whose glad they're done with the DATs after reading stuff like this? I AM! haha jk jk...we'll all get there soon...dont worry! but yea...the answer is D for sure. hydrogen bonding is a big player on the DATs!

wow I haven't studied for it and i got it right! is this question considered easy or hard compared to other chem questions?
