Question

Of the six compounds, which is the most soluble and which one is the least soluble in water? Explain your answers.
a. ethane C2H6
b. ethanol C2H6O (CH3CH2OH)
c. ethanoic acid C2H4O2 (CH3COOH)
d. methoxymethane C2H6O (CH3OCH3)
e. octane C8H18
f. 1-octanol C8H18O (CH3CH2CH2CH2CH2CH2CH2CH2OH)

Answer 1

The most soluble should be ethanoic acid, it has a low molecular weight, its molecule is strongly polar, has a hydrophilic group.
A soluble wording is octane, its molecule is non-polar, has a large molecular weight and does not have hydrophilic groups
