Answer:
The following alcohols will be soluble in water:
2-propanol
Explanation:
Alcohols are soluble in water and have high boiling point because they form hydrogen-bond with water molecules
The solubility decreases with increase in size of alkyl/aryl (hydrophobic)
groups.
This is because with Higher molecules the extent of Hydrogen bonding decreases due to more hydrophobic interactions(water repelling)
Branching reduces the surface area of the molecules , hence reduces the hydrophobic interaction . Thus increases the solubility or boiling point.
The lower molecular mass alcohols are miscible with water in all proportions.
3-hexanol = 6-Carbon = minimum solubility
2-propanol = 3 carbon = Maximum solubility
2-butanol = 4 carbon
2-pentanol = 5 carbon
Thus 2- Propanol is olube in water.
Here Branching does not affect solubility because each molecule id equally branched.
