true
false
Which alcohol is most soluble in water?
propan-1-ol
pentan-2-ol
isobutyl alcohol
tert-butyl alcohol.
Which is NOT a physical property of alcohols or phenols?
Phenols are generally only slightly soluble in water.
The solubilities of normal primary alcohols in water decrease with increasing molecular weight.
The hydroxyl group of an alcohol is nonpolar.
Due to hydrogen bonding, boiling points of alcohols are much higher than those of corresponding alkanes.
Why is ethanol more soluble in water than propanol?
because can form more hydrogen bond with water molecules
because can form dimer structure
because less hydrophobic areas
because more hydrophilic areas
In alcohols, the –OH group is covalently bonded to a saturated hydrocarbon.
