Which of the following compounds will be most soluble in methanol (CH3OH)?
a) carbon tetrafluoride (CF4) |
b) pentane (CH3CH2CH2CH2CH3) |
c) acetone (CH3COCH3) |
d)toluene (C7H8) |
e) None of these compounds should be soluble in methanol. |
c) acetone (CH3COCH3)
Acetone is most soluble in methanol. Because aceetone have oxygen which forms hydrogen bond methanol.
Other compounds are hydrophobic in nature Hence they would be more soluble in the non-polar solvent than methanol.
