Which one of the following alcohols will be soluble in water?
3-hexanol
2-propanol
2-butanol
2-pentanol

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.

the molecules move in straight line until they collide with each other or with the walls of the container. collisions are perfectly elastic; when two molecules collide, they change their directions and kinetic energies, but the total kinetic energy is conserved.
