DAT Tomorrow -- Quick Solubility question

Kaplan is telling me that CH3CH2OH is more soluble than CH3CH2CH2OH, but I have read that increasing the chain length and MW increases solubility. Which is correct?

 

[wantVCUdental]

Kaplan is correct

more R = less soluble

your R is non-polar so you want to avoid it as much as you can. Alcohol only with short CH chains are water soluble

More R will make the molecule to not be soluble anymore....like in soap which I think it's an ester, but it has a big carbon chain that makes it to be non-polar...that's why when ur handsare oily(non-polar) and wash them with water u can't clean ur hands....so just remember MORE CH bonds-->less polar=less soluble

GOOD LUCK tomorrow....I have my DAT on OCT 9th.

chain length and mw increases boiling pt

sure ur not confusing the two?

Thanks for all the help... That definately makes more sense.
