Question

Is propanol soluble in water?

Answer 1

Hint:Propanol is a compound or a member of alcohols and it is the third member of the alcohols which means there is a total of three carbon atoms in propanol and there is a hydroxyl group at the end of the chain (-OH). The hydroxyl group contains oxygen atoms which can form hydrogen bonding in the water so it is soluble in water. But its solubility also depends on the length of the hydrocarbon chain in the compound.

Complete step-by-step answer:Water is a universal solvent that is used to make solutions for many purposes because most things are soluble in water. When we see any organic compound be soluble in water, we check the polarity or check the formation of the hydrogen bonding.
Propanol is a compound or a member of alcohols and it is the third member of the alcohols which means there are a total of three carbon atoms in propanol and there is a hydroxyl group at the end of the chain (-OH). The formula of propanol is $C{{H}_{3}}-C{{H}_{2}}-C{{H}_{2}}-OH$.
 The hydroxyl group contains oxygen atoms which can form hydrogen bonding in the water so it is soluble in water. But its solubility also depends on the length of the hydrocarbon chain in the compound.
Usually from the alcohols, methanol and ethanol have high solubility in the water, propanol and butanol are soluble but not as methanol and ethanol because the hydrocarbon part in propanol and butanol are large.

Yes, propanol is soluble in water.

Note:In aliphatic hydrocarbons, as the chain length increases the solubility decreases, but if there is branching in the hydrocarbon, then the solubility will increase because the surface area of the hydrocarbon decreases.
